Why CO2 Monitoring Makes a Difference

The presence of CO2 directly affects how people feel and function. In learning environments, it influences comprehension and memory. In offices, it impacts productivity and decision-making. In hospitals and elderly care centers, it plays a role in patient safety and recovery outcomes. Beyond human wellbeing, CO2 data also helps optimize ventilation systems, lowering energy consumption and supporting sustainability efforts. By acting on this data, organizations not only improve comfort but also reduce costs and align with environmental goals.

Choosing the Right CO2 Monitor

When selecting a CO2 monitor, it’s important to go beyond just the basics. Accuracy is critical, but the ability to measure multiple parameters such as particulate matter, humidity, VOCs, and noise makes the data more valuable. Access to both real-time and historical data ensures that decisions can be made quickly while also tracking long-term patterns. Connectivity plays a major role too: whether through BLE, Wi-Fi, or cellular, the monitor must integrate seamlessly with HVAC systems and digital dashboards. Lastly, scalability is essential — the monitor should work just as effectively in a single room as it does across large campuses or multi-site operations.

For today’s facility managers, the invisible often becomes the most urgent challenge. Indoor air quality (IAQ) is one of those challenges: it affects not only compliance reports but also the health, focus, and productivity of everyone inside a building. Poor IAQ can quietly undermine comfort and efficiency, yet many managers still lack the tools to see what’s really happening.

HibouAir changes that by making air quality measurable, transparent, and actionable. Below are four scenarios that illustrate how HibouAir helps facility managers take control.

Case 1: Meeting Rooms That Drain Productivity

Problem:
A corporate office noticed recurring complaints during long meetings — employees felt sluggish, and concentration levels dropped quickly. Ventilation schedules were already optimized for the whole building, but something wasn’t right.

Solution with HibouAir:
When the facility manager installed the HibouAir Duo, which measures CO₂, particulate matter, VOCs, humidity, temperature, and noise, the data revealed that CO₂ levels in closed meeting rooms often rose well above 1000 ppm.

Impact:
Armed with this insight, the manager fine-tuned ventilation to target only the spaces where air quality degraded fastest. Employees noticed sharper focus and fewer headaches during meetings, while the company saved energy by avoiding unnecessary whole-building ventilation.

Case 2: Making Compliance and ESG Audits Easier

Problem:
Managing several office sites, a facility team struggled with ESG reporting. Collecting and consolidating air quality data across locations was time-consuming, and the process lacked transparency for auditors.

Solution with HibouAir:
By moving to the HibouAir Cloud Monitoring Solution, the manager unified all data into one centralized dashboard. Real-time and historical records were now automatically logged and ready for reporting.

The HibouAir Advantage

What unites these stories is a simple truth: you cannot manage what you cannot measure. HibouAir provides facility managers with the clarity they need, whether through a standalone plug-and-play sensor, the versatile HibouAir Duo, or a scalable cloud solution.

With real-time and historical insights into CO2, PM, VOC, temperature, humidity, and noise, HibouAir transforms invisible risks into actionable data. Managers save energy, improve compliance, and most importantly, create healthier spaces where people can thrive.

Modern buildings are expected to do more than just provide shelter—they must deliver comfort, safety, and efficiency. At the center of this responsibility is the HVAC system. But without accurate insights into indoor air conditions, HVAC systems often operate inefficiently, wasting energy and compromising well-being.

This is where air quality data from HibouAir makes all the difference.

Turning HVAC Systems Into Intelligent Systems

Traditional HVAC controls are usually based on temperature or fixed schedules. While this offers a basic level of comfort, it overlooks critical factors such as:

• CO₂ concentration, a clear signal of occupancy and ventilation needs
• Particulate matter (PM), an indicator of harmful pollutants and dust
• Humidity and VOCs, key to preventing mold and ensuring healthy environments

By combining these metrics with HVAC operations, buildings can respond dynamically—ventilating when needed and conserving energy when conditions are already optimal.

Reducing Costs While Improving Indoor Health

Energy costs are one of the biggest challenges in facility management. Over-ventilation wastes energy, while under-ventilation compromises health and productivity. With real-time monitoring from HibouAir standalone devices and cloud platforms, HVAC systems can achieve the right balance—ensuring healthier air while cutting unnecessary energy use.

Ensuring healthy indoor air quality has become a core part of workplace safety, and carbon dioxide (CO2) monitoring plays a critical role in this effort. CO2 is a colorless, odorless gas that builds up naturally in occupied indoor spaces due to human exhalation and other sources. High CO2 levels are not usually directly toxic at the concentrations found in offices, but they serve as an important indicator of ventilation effectiveness and overall indoor air quality. Inadequate ventilation can lead to a stuffy, uncomfortable environment and even affect employees’ well-being and productivity.

Why Monitor CO2 in the Workplace?

Monitoring CO2 provides a quick way to gauge if a workspace is getting enough fresh air. Since people constantly exhale CO2, indoor levels tend to rise in crowded or poorly ventilated areas. Outdoor air is roughly 400 ppm (parts per million) CO2, but indoor concentrations can range from a few hundred ppm up to over 1,000 ppm in occupied rooms with limited ventilation. The key factors are the number of people, the time spent in the space, and the amount of fresh air being supplied. Measuring CO2 is an indirect ventilation check – if CO2 is accumulating, it suggests the space isn’t getting enough outside air for the number of occupants.

Safe CO2 Levels and Official Guidelines

Workplace safety organizations and building standards provide guidance on acceptable indoor CO2 concentrations. Here are key benchmarks from renowned authorities:

OSHA Permissible Exposure Limit (PEL): OSHA (Occupational Safety and Health Administration) primarily treats CO2 as an asphyxiant gas hazard at very high levels. OSHA’s occupational exposure limit for CO2 is 5,000 ppm averaged over an 8-hour workday. This is a safety threshold meant to prevent acute CO2 toxicity in industrial settings – levels this high are uncommon in normal offices. (For reference, some guidelines also note a short-term limit around 30,000 ppm for 15 minutes, and concentrations ~40,000 ppm are immediately dangerous to life and health.) While 5,000 ppm is the legal limit, best practice is to keep indoor CO2 far below this ceiling in everyday workplaces for comfort and wellness.

ASHRAE Ventilation Standards: Rather than a strict CO2 limit, ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) sets ventilation rate standards to ensure adequate fresh air per person. For example, ASHRAE Standard 62.1 recommends around 15–20 cubic feet per minute of outdoor air per person in offices and classrooms, which generally keeps indoor CO2 below about 1,000 ppm for most spaces. 1,000 ppm has long been used as a rule-of-thumb comfort target for CO2. While ASHRAE does not explicitly require staying under 1000 ppm in its standards, maintaining roughly 600–1,000 ppm indicates that ventilation is likely sufficient for occupant comfort. In fact, ventilation rates that keep CO2 under 1000 ppm tend to create indoor conditions acceptable to most people.

WHO and Public Health Guidance: In the context of infection control (e.g. COVID-19), health authorities emphasize ventilation. The World Health Organization (WHO) recommends providing at least 10 liters/second of fresh air per person in offices (roughly aligning with ASHRAE’s rates) to reduce respiratory aerosol risks. Since measuring airflow directly can be technical, experts often use CO2 as a proxy. The UK’s SAGE group and other experts advise keeping CO2 below 1000 ppm in general indoor spaces, and below ~800 ppm in higher-risk, high-occupancy settings like gyms or choir rooms. If indoor CO2 ever reaches 1500 ppm or more, it’s considered a red flag indicating very poor ventilation that should be addressed immediately.

CDC Recommendations: The U.S. CDC has recently issued practical ventilation guidelines using CO2 monitors. “A portable CO2 monitor can help determine how stale or fresh the air is. Readings above 800 ppm suggest you may need to bring more fresh air into the space,” according to the CDC. In other words, ~800 ppm CO2 is a benchmark for good ventilation in many scenarios. The CDC advises establishing a baseline CO2 level for each room under optimal ventilation, and if readings exceed about 110% of that baseline, there may be an HVAC issue or ventilation reduction that needs correction. This approach encourages proactive monitoring to ensure ventilation systems keep performing well over time.

By considering these guidelines together, many organizations choose a tiered approach to CO2 levels in workplaces:

• Optimal: 600–800 ppm (excellent ventilation, akin to outdoor-fresh air in the room)
• Acceptable: 800–1000 ppm (generally adequate ventilation for most situations)
• Poor: 1000–1500 ppm (needs improvement – likely causing stuffiness and affecting comfort)
• Action Required: >1500 ppm (inadequate ventilation – take immediate steps to increase fresh air).

Effects of Elevated CO2 on Health and Performance

High indoor CO2 levels affect comfort, focus, and overall air quality. Research shows that even moderate levels around 1000 ppm can impair decision-making and concentration, while levels above 1500–2000 ppm often cause drowsiness, headaches, and fatigue. Prolonged exposure to several thousand ppm may lead to dizziness or nausea, and extremely high levels pose serious health risks. More commonly, elevated CO2 signals poor ventilation, which allows other pollutants to build up and results in complaints of stuffy, uncomfortable air. Keeping CO2 low ensures employees stay alert, productive, and healthier.

Best Practices for Managing Indoor CO2

Maintaining safe CO2 levels starts with proper ventilation—ensuring HVAC systems deliver enough fresh air and are regularly maintained. Where possible, natural ventilation or portable air cleaners can also help. Continuous CO2 monitoring provides real-time insight into air quality, allowing facilities to spot problem areas and act quickly. Setting clear thresholds, such as alerts when levels exceed 1000 ppm, ensures issues are addressed before they escalate. Using data to adjust ventilation, manage occupancy, and educate staff about CO2 monitoring fosters a healthier environment. Ideally, CO2 should remain below 800–1000 ppm to keep workplaces fresh, safe, and comfortable.

CO2 Monitoring Solutions: Devices Like HibouAir

Technology has made it easier than ever to continuously monitor indoor air quality. There are now plug-and-play CO2 monitoring devices that can be deployed in workplaces without complex installation. For example, HibouAir is an indoor air quality monitor that provides real-time measurements of CO2 along with other environmental parameters. HibouAir’s multi-sensor design tracks carbon dioxide levels, temperature, humidity, ambient light, atmospheric pressure, and volatile organic compounds (VOCs) to give a complete snapshot of your indoor environment.

Devices like this are compact and wireless, connecting via Bluetooth or Wi-Fi for easy data access. With continuous monitoring, facility managers can set up alerts when CO2 approaches set thresholds, and view trends over hours or days to identify ventilation issues. For instance, if CO2 steadily rises every afternoon in a certain area, you’ll spot it in the data and can investigate (perhaps an air damper that isn’t opening or an overcrowded meeting area). By keeping CO2 levels in check, organizations can optimize the indoor space for productivity, comfort, and well-being. In other words, a good monitor not only warns of potential safety issues but also empowers you to fine-tune the environment for maximum occupant comfort and efficiency.

CO2 monitoring has become an essential component of modern workplace safety and wellness programs. It provides a simple, objective measure of whether your indoor spaces are well-ventilated and healthy. By adhering to guidelines from OSHA, ASHRAE, WHO and others, organizations can maintain CO2 at levels that ensure worker safety and comfort – typically keeping concentrations under about 1000 ppm, with 600–800 ppm as a gold standard for optimal ventilation. Regular monitoring with reliable devices helps catch any ventilation issues early, allowing facility managers to address them before they impact employees. The result is a workplace that not only meets safety requirements but also supports employee alertness, productivity, and overall well-being. In short, CO2 monitors are valuable tools for creating healthier, safer work environments, and implementing them alongside good ventilation practices is a smart investment in your organization’s most important asset – its people.

Most of us spend the majority of our time indoors, yet the quality of the air inside is often overlooked. Research from the World Health Organization shows that almost everyone in the world lives in places where air quality does not fully meet its recommended guidelines. Indoor air can be affected by fine particles, gases from outdoor pollution, and everyday sources such as cleaning products or building materials. While regulations and standards exist to help limit these pollutants, raising awareness and taking simple actions indoors—like improving ventilation or reducing sources of emissions—play an equally important role in creating healthier environments.

Regulators use air‑quality standards to limit pollutants. For example, the WHO recommends annual average limits of 10 µg/m³ for PM2.5 (fine particles) and 20 µg/m³ for PM10. These guidelines are stricter than current European Union limits (25 µg/m³ for PM2.5 and 40 µg/m³ for PM10), underscoring the need for vigilance even in regions with air‑quality regulations.

Raising awareness through education and public participation

Making indoor air healthier isn’t just a job for government agencies or scientists. Education and public participation are essential. When families, teachers or office managers understand what pollutants are and how to reduce them, they can make everyday choices—like improving ventilation or choosing low‑emission products—that lead to cleaner air. Workshops, school projects and community‑led air quality projects give people first‑hand experience with monitoring. Collecting air‑quality data in homes, classrooms and workplaces and sharing it with neighbours or local officials builds awareness and supports informed decision‑making.

Public participation also helps fill gaps in official data. In many places there are few government sensors, especially indoors. Networks of small monitors operated by communities can identify problem areas, such as poorly ventilated rooms or local pollution hotspots, and support targeted solutions. Real‑time data also allow people to see immediate improvements when they open a window or adjust a ventilation system.

Using simple tools to support community projects

To take part in these projects, people need easy‑to‑use tools. Consumer devices like HibouAir offer a way for anyone to measure what they’re breathing. The HibouAir DUO air quality monitor combines sensors for carbon dioxide, fine dust (PM1.0, PM2.5, PM10), volatile organic compounds, temperature and humidity, providing accurate, real‑time data in a compact package. It connects via Bluetooth, Wi‑Fi or cellular networks. Users can view and export their readings using a mobile application or simple dashboard.

This plug‑and‑play design makes HibouAir suitable for classrooms, homes and small businesses. Teachers can use it during lessons to show how CO2 levels rise when many students are in a room and fall when windows are opened. Community groups can deploy multiple units in different rooms to identify areas with high pollutant levels. Because the data can be shared easily, it becomes a starting point for discussions about improving ventilation, choosing low‑VOC materials or advocating for cleaner outdoor air.

Turning information into action

Numbers alone don’t clean the air. Once people see the data, they can take simple steps: opening windows more often, reducing indoor sources of fumes and dust, or asking building managers to maintain heating and ventilation systems. Over time, public awareness and community‑led monitoring can encourage municipalities to tighten air‑quality standards and align with WHO guidelines, which would prevent thousands of premature deaths.

Air pollution is a major health risk worldwide, but it often goes unnoticed inside our own walls. By educating ourselves and participating in community projects, we can make the invisible visible. Tools like HibouAir helps anyone to understand their indoor air and take meaningful steps to improve it. When public participation, accessible technology and clear health guidelines come together, healthier air becomes a shared goal that everyone can work toward.

Indoor air quality (IAQ) is a dynamic factor influenced by changing occupancy, outdoor pollution levels, ventilation performance, weather, and daily routines. Treating IAQ as static often leads to unexpected issues such as CO2 spikes during meetings or particulate matter surges after cleaning activities. Instead of waiting for problems to occur, predictive analytics enables facility managers to forecast air quality trends and take action before comfort, health, or compliance is compromised. With solutions like the HibouAir Desktop Air Quality Monitoring Solution and HibouAir Cloud Platform, organizations can easily collect and analyze the data required for accurate predictions.

Why Prediction Beats Reaction

Predictive analytics allows managers to anticipate poor air quality instead of responding after conditions deteriorate. For instance, forecasting CO2 and particulate matter trends helps prevent headaches, fatigue, and allergy flare-ups before they occur. This proactive approach also enables targeted HVAC use, increasing airflow only when forecasts indicate upcoming deterioration—saving energy without sacrificing comfort. From a compliance perspective, predictive models provide traceable, time-series forecasts and anomaly reports that simplify ESG reporting and audits. Businesses adopting this strategy, particularly those using advanced monitoring tools like the HibouAir Standalone Device, can maintain high air quality while optimizing operational efficiency.

The Data That Makes IAQ Predictable

Accurate IAQ prediction depends on high-quality, multi-parameter data. Core environmental indicators—CO2 levels, particulate matter concentrations (PM1, PM2.5, PM10), temperature, humidity, volatile organic compounds (VOCs), pressure, and even ambient noise—provide the foundation. Contextual inputs such as room occupancy schedules, ventilation settings, and cleaning activities further refine model accuracy. The ability to collect and integrate all these inputs into one platform is what makes HibouAir’s Analytical Dashboard a vital tool for predictive analysis.

Turning Predictions into Action

Once forecasts are in place, facility managers can use them to guide interventions. For example, ventilation can be pre-emptively increased before predicted CO₂ spikes, reducing energy consumption compared to continuous operation. Cleaning schedules can be adjusted to times when forecasts indicate better particulate dispersion. In facilities with sensitive equipment or artifacts—such as museums—these predictive insights can be combined with specialized monitoring approaches discussed in our article on Monitoring Air Quality in Museums. Predictive maintenance is also possible; if residual trends suggest filtration efficiency is declining, maintenance can be scheduled before air quality drops.

How HibouAir Makes This Possible

HibouAir offers a complete ecosystem for predictive IAQ management. Its multi-sensor devices measure CO2, particulates, VOCs, temperature, humidity, noise, and more with high precision, delivering the rich datasets predictive models require. The HibouAir Analytical Dashboard provides real-time and historical visualization to identify patterns and validate forecasts. The HibouAir Portal offers fleet-wide monitoring and analysis, making it easy to compare multiple sites and correlate indoor conditions with outdoor influences. Features like historical data visualization, real-time alerts, automated weekly reports, and CSV export ensure that both daily operations and long-term analysis are covered.

A Practical Workflow

A straightforward way to begin is by deploying HibouAir devices across all relevant spaces, tagging them with metadata such as capacity, function, and ventilation type. After two to four weeks of baseline data collection, patterns can be established using the dashboard, with anomalies cleaned from the dataset. From there, forecasting models can be implemented, starting with simpler statistical approaches and advancing to machine learning as the dataset grows. Predictions can be tied to automated alerts via the HibouAir Portal, enabling interventions such as pre-ventilation before predicted peaks. Weekly and monthly reports provide stakeholders with evidence of both compliance and improvement.

Tracking Success

Measuring success in predictive IAQ management involves tracking key performance indicators like time spent within target thresholds, the number of predicted high-risk hours, and the precision of alerts. The HibouAir Cloud Enterprise Solution makes it simple to track and visualize these metrics across a portfolio of buildings. Over time, improved IAQ stability and reduced intervention costs prove the value of predictive analytics.

Privacy and Data Governance

Since IAQ data can imply occupancy levels, HibouAir ensures that monitoring remains privacy-conscious by aggregating readings at the zone level and providing secure cloud access via HibouAir Cloud Lite or Enterprise platforms.

The future of IAQ prediction lies in integration—linking HibouAir forecasts with building management systems for fully automated ventilation control, incorporating weather forecasts to anticipate infiltration effects, and applying root-cause analysis when anomalies are detected. As explored in our guide on Improving Indoor Air Quality in Offices, such predictive strategies enhance comfort, reduce costs, and improve compliance. HibouAir’s connected ecosystem ensures that organizations of any size can adopt predictive analytics without the need for complex, custom-built systems.

Every day, we unknowingly inhale thousands of microscopic plastic particles. These airborne microplastics—tiny fragments from degraded plastics, synthetic fibers, and everyday products—pose a growing threat to human health. A recent study estimates that humans inhale up to 70,000 microplastic particles per day in typical indoor environments¹. The situation is even more intense in enclosed spaces like cars, where microplastic concentrations can reach 2,238 particles per cubic meter, with 94% of them smaller than 10 micrometers—small enough to penetrate deep into the lungs².

The Hidden Threat Indoors

Indoor air typically contains 8 times more airborne microplastics than outdoor environments³. This is due to common household items—such as carpets, curtains, furniture, and even synthetic clothing—slowly breaking down and releasing plastic particles into the air. These particles become suspended in household dust and can remain airborne for extended periods, especially in poorly ventilated rooms.

The problem extends beyond homes. Offices, schools, gyms, and vehicles also act as microplastic hot zones. The constant shedding from electronics, furnishings, and synthetic materials creates a near-invisible cloud of plastic particles that we breathe in daily.

Health Risks of Breathing Plastic

Microplastics and nanoplastics can easily enter the body through inhalation. Recent research links these particles to respiratory inflammation, digestive issues, hormonal disruption⁴. Nanoplastics—particles smaller than 1 micrometer—are especially dangerous because they can cross biological barriers and accumulate in critical organs such as the brain, lungs, and reproductive system⁵.

Moreover, many microplastics contain chemical additives like phthalates and bisphenol A (BPA), which have been shown to interfere with hormonal and immune systems⁶. While more long-term studies are needed, current evidence strongly suggests that regular exposure—especially indoors—poses a real and escalating health concern.

Where HibouAir Fits In

Although HibouAir doesn’t directly detect microplastic particles by type, it provides accurate, real-time monitoring of particulate matter (PM1.0, PM2.5, PM10)—size categories that include most microplastic fibers and fragments. By identifying particle concentration spikes in the air, HibouAir helps users recognize when conditions are likely contributing to higher microplastic exposure.

In addition to PM data, HibouAir also tracks CO₂, VOCs (Volatile Organic Compounds), temperature, humidity, and more. These environmental indicators offer important context: high humidity and stagnant air, for instance, can encourage microplastic particles to stay airborne longer, increasing the likelihood of inhalation.

HibouAir’s platform includes mobile application, and cloud-based dashboards that allow users to review air quality trends, set thresholds, and receive alerts—making it easier than ever to monitor and improve the air in homes, classrooms, and workplaces.

Simple Steps Toward Cleaner Air

Experts recommend minimizing microplastic exposure through better indoor hygiene, natural materials, and air filtration. Regular vacuuming with HEPA filters, reducing synthetic fabrics and plastic packaging, and increasing ventilation all play a role. HibouAir complements these practices by providing a continuous feedback loop—helping users evaluate whether actions like opening windows or using purifiers are truly effective in reducing airborne particulate levels.

For example, one study found that indoor PM2.5 levels dropped by 58% when HEPA filters were used during wildfire events⁷. This same principle can be applied to help reduce microplastic exposure—especially since many microplastics fall within the same particle size range.

Microplastics in the air are a silent, invisible threat—and the majority of that exposure happens indoors. While we can’t see them, we can monitor the conditions that allow them to thrive. HibouAir helps users to do just that, offering the tools to monitor, respond to, and reduce the health risks of poor indoor air quality.

A recent study by Imperial College London has confirmed a concerning truth: closing classroom windows does not stop outdoor air pollution from entering schools. Conducted under the SAMHE (Schools’ Air quality Monitoring for Health and Education) project, the study monitored nearly 500 classrooms across the UK and revealed that outdoor air pollution is the primary contributor to indoor air quality issues in schools.

On 6% of the school days, outdoor particle pollution exceeded World Health Organization (WHO) daily guidelines—and these high-pollution days were responsible for a striking 17% of the total indoor pollution exposure over the year (WHO guidelines).

More Ventilation? Not the Solution Alone

Some schools try to address air quality concerns by reducing ventilation on polluted days. However, Dr Alice Handy of the SAMHE team explains that “reducing ventilation will not stop outdoor PM2.5 from entering classrooms.” Even during weekends when schools were closed, pollution levels remained high inside classrooms, especially around events like fireworks night (Dr. Handy’s publication profile).

Moreover, good ventilation is critical for keeping CO₂ levels low, which plays a key role in improving concentration and reducing the risk of airborne infections among students.

HibouAir: Real-Time Insights for Better Air

These findings underscore the urgent need for reliable, real-time air quality monitoring inside classrooms. That’s exactly where HibouAir makes a difference.

HibouAir offers a compact, plug-and-play air quality monitor that continuously tracks: PM1.0 / PM2.5 / PM10, CO₂ and VOCs, Temperature, humidity, and pressure, Noise levels.

This enables schools to respond in real time, adjusting ventilation, purifiers, or class schedules based on current air quality conditions—rather than assumptions.

Sensors and Filters: A Smart Combination

In the same SAMHE study, air filters were tested in an additional 300 classrooms. The result? A 29% reduction in particle pollution compared with nearby schools without filters (poster report).

However, Dr Samuel Wood of the research team noted that even with filters, “outdoor air quality was still the leading driver of classroom pollution” (Dr. Wood’s profile). Filters helped, but without real-time monitoring, schools remain unaware of when air quality actually improves or worsens.

HibouAir bridges this gap by providing data that validates the effectiveness of purification systems and alerts staff during high-risk periods.

Protecting Students Beyond the Classroom

Children are exposed to pollutants not just at school, but also at home—from sources like cooking with gas, personal care products, wood burners, and cigarettes. Research also shows that the journey to school can expose children to more traffic-related pollution than they encounter indoors (ScienceDirect article).

These findings further highlight the value of evidence-based school policies, such as no-idling zones, “school streets,” and fossil fuel reduction efforts.

Take Action: Monitor and Improve

HibouAir helps schools with the real-time data they need to take proactive and informed action. By setting customizable thresholds, schools can receive instant alerts when pollution levels exceed safe limits, ensuring timely responses to protect students and staff. The system also allows for direct comparison between indoor and outdoor air quality, offering valuable insight into how well school buildings shield against external pollutants. With this data, administrators can optimize the use of air purifiers and ventilation systems more effectively, adjusting them based on actual conditions rather than assumptions. Furthermore, HibouAir enables schools to evaluate the impact of sustainability initiatives—such as green infrastructure or reduced traffic zones—by providing measurable evidence of their effectiveness in improving air quality.

Without reliable monitoring, schools are navigating air quality blindly. HibouAir makes that data visible, actionable, and easy to understand.

The classroom should be a space for learning and health—not hidden exposure. As the SAMHE study confirms, pollution isn’t just an outdoor problem, and closing the windows is not the fix.

With HibouAir, schools gain the insight they need to create healthier, more focused learning environments. Let’s build a future where every school knows the air their students are breathing.

As smart environments become more prevalent across homes, offices, and educational institutions, the need to understand and act on indoor air quality has never been more important. While automation platforms like Node-RED have made it easier to connect various devices and services, visualizing live air quality data is often overlooked.

That’s where HibouAir comes in—a powerful, plug-and-play air quality monitoring device that can be easily integrated into your Node-RED dashboard. With this integration, you can receive real-time air quality data directly in your browser, enabling informed decisions, automated actions, and healthier indoor environments.

What is Node-RED?

Node-RED is an open-source, flow-based development tool designed for connecting hardware devices, APIs, and services in a visual way. Developed originally by IBM, it allows users to drag and drop nodes, wire them together, and build automation flows—all with minimal coding.

With support for serial communication and BLE workflows, Node-RED is ideal for developers, researchers, and system integrators who want to visualize sensor data or create smart automation flows.

Creating a Real-Time Air Quality Dashboard Using Node-RED and HibouAir

With just a few tools, you can build your own live air quality dashboard using HibouAir and a BLE USB dongle such as BleuIO. The dashboard will show real-time data like CO2, temperature, and humidity, updating automatically as your environment changes.

We’ve created a detailed tutorial on the BleuIO website that shows how to:

• Scan for BLE advertisements from HibouAir
• Decode the advertisement payloads
• Visualize the data using Node-RED’s dashboard features

Once set up, your dashboard will provide a dynamic view of your indoor air quality, refreshed every few seconds.
