Understanding the importance of indoor air quality

Indoor air quality is fundamental to our health and well-being. Studies show that indoor pollution often exceeds outdoor pollution, especially in urban areas. Thanks to technological advances, particle sensors are now able to detect various pollutants such as CO2, fine particles and volatile organic compounds.

Impact on health and well-being

Poor air quality can lead to allergies, respiratory problems and reduced productivity. ANSES points out that indoor pollution is responsible for thousands of deaths every year in France. Children and the elderly are most at risk.

Main sources of indoor pollution

Several sources contribute to indoor pollution:

  • Heating with wood
  • Cooking food
  • Vehicle emissions
  • Activities such as lawn mowing

Aerosol control is crucial, as fine PM2.5 particles can seriously affect the lungs.

Standards and regulations in force

Strict laws govern air quality in various buildings. The use of IoT sensors ensures real-time monitoring. With 30 years' experience, Syscom-Prorep offers reliable solutions to ensure a healthier indoor environment.

Types of air pollutants to be monitored

Air pollution monitoring requires careful attention to several pollutants. Fine particles PM2.5 and PM10 are the most important to measure. They come mainly from wood heating, road traffic and urban construction sites.

Particularly harmful, PM2.5 can penetrate deep into the lungs. Prolonged exposure increases the risk of respiratory and cardiovascular disease. Near major roads, their concentration can be much higher than in more remote areas.

  • Carbon dioxide (CO2)
  • Volatile organic compounds (VOCs)
  • Carbon monoxide (CO)
  • Nitrogen oxides (NOx)
  • Ozone (O3)

France is committed to ambitious emission reduction targets. For example, a 57% reduction in PM2.5 is planned by 2030 compared with 2005. To achieve this, the measurement of PM2.5 and PM10 is crucial, as is increased monitoring of overall air pollution.

How a fine particle detector works

Fine particle detectors play a crucial role in monitoring indoor air quality. Thanks to their cutting-edge technology, they carry out a meticulous analysis of the surrounding air. This data is essential to our well-being.

Detection technologies used

The modern particle sensor is based on optical scattering. An infrared LED emits light, while a detector records the flashes generated by the particles. The intensity of these flashes indicates the size of the particles, thus distinguishing PM₁₀ from PM₁.

Measurement accuracy and reliability

The accuracy of particle sensors is comparable to that of top-of-the-range devices. They assess the Air Quality Index (AQI) on a scale of 0 to 500, while some models go even further, detecting CO2, temperature and humidity for a comprehensive analysis of ambient air.

Calibration and maintenance

Regular calibration is essential to ensure reliable measurements. Maintenance includes cleaning the sensor and checking its operation. It is important to note that excessive humidity can be interpreted as particulate matter, influencing the results.

Integrated into building management systems, these detectors enable constant monitoring. They facilitate the identification and implementation of actions to improve indoor air quality.

Air quality sensor selection criteria

Selecting a fine particle detector requires careful analysis. Measurement accuracy is essential. NDIR detectors provide an accuracy of +/- 3%, while PAS achieves +/- 8%. Solid-state sensors are less accurate, but are suitable for basic domestic use.

Pollutant detection capability is paramount. A quality detector should measure PM2.5, CO2, VOCs, temperature and humidity. Models like the Airthings View Plus even detect radon, essential in high-risk areas.

Connectivity plays a crucial role. Sensors compatible with Alexa, Google Home or Apple simplify home automation integration. The interface must be intuitive for ease of use. Energy autonomy varies, with some models running on batteries for weeks on end.

The coverage range is also decisive. Some sensors monitor up to 100 m². Instant notification means you can act without delay. Companies like Syscom-Prorep offer customized solutions tailored to your requirements.

Finally, durability, software updates and technical support are crucial to long-term reliability. Choose an environmentally-friendly device to support your green initiatives.

Data analysis and interpretation

Ambient air analysis requires in-depth expertise in the data captured by fine particle detectors. Modern sensors, such as the SDS011, continuously measure PM2.5 and PM10 levels. They transmit this information in real time via the LoRaWAN network. The data is stored in a MongoDB database, making it easy to process.

Pollution is monitored at several levels. A study in the Île-de-France region used portable micro-sensors with 88 participants over 7 days. Pollutant levels ranged from 14 to 64 μg/m³, depending on the environment. This monitoring makes it possible to identify emission sources and assess the impact of ventilation on indoor air quality.

Interpreting the data requires specialized expertise. The ICONE index, created by CSTB, is a reliable method for assessing air renewal in buildings. Artificial intelligence tools, such as ARIMA models, help to fill data gaps. They enable high-resolution analysis of individual exposures. A web application with mapping makes visualization and interpretation of results more accessible, improving understanding of air quality.

Maintenance and service life

A fine particle detector requires regular maintenance to ensure accurate measurements. The frequency of calibration depends on the environment: monthly in a clean environment, more frequent in contaminated areas. External cleaning should be carried out with a dry cloth to protect the electronic components.

Sensor technology plays a crucial role in service life. Modern particle sensors operate continuously, ensuring a service life in excess of 10 years. Some models, equipped with powered multi-sensor probes, are maintenance-free for this period.

  • Set detection interval between 10 and 30 minutes
