Best indoor pm2 5 sensor application areas
PM is the abbreviation of “particulate matter”. Those suspended in the air with a diameter of 2.5 microns or less are called PM2.5, also known as fine particulate matter. Compared with coarser particles, fine particles contain a larger amount of toxic and harmful substances, can stay in the atmosphere for a longer time, and are transported over longer distances. They have a greater impact on the atmospheric environment and human health, and are responsible for causing black The main killers of lung disease and smog days.
Smog is an aerosol composed of dust in the air that floats for a long time and combines with water vapor. It affects the atmospheric environment and also affects people’s respiratory health. With the arrival of autumn and winter, some cities with developed industries and dense populations are prone to haze weather due to air pollution.
In order to monitor air quality in a timely manner and reduce the harm of dust to people, the indoor pm2 5 sensor can show its talents. Let’s take a look at the fields in which PM2.5 sensors can be applied.
1. Portable air quality detector
In recent years, air quality has attracted much attention. People can only see the haze, but do not know the extent of the pollution. Therefore, more and more people choose to use air detectors. Air detectors can digitize the level of air pollutants, making air quality pollution data visible.
Indoor pm2 5 sensor is one of the core components of the air detector. It displays the real-time concentration of PM2.5 in the air through the detection output signal of the PM2.5 sensor.
2. Fresh air system
Dust particles in the air will enter the human respiratory tract following breathing, causing great harm to human health. The higher the concentration of PM2.5 in the air, the more serious the air pollution will be. One of the most important functions of the fresh air system is to intelligently filter PM2.5 particles in the air. The indoor PM2 5 sensor inside is the key to sensing dust particles in the air.
3. Air purifier
As the main force in eliminating indoor pollutants, air purifiers naturally remove indoor dust as their basic function. The indoor pm2 5 sensor is undoubtedly the source of dust removal by air purifiers. Currently, most air purifiers on the market use Laser Dust Sensor to detect indoor dust.
4. Production environment of industrial and mining enterprises
Dust is generated during various production processes in industrial and mining enterprises: such as drilling, blasting, excavation and cutting, topping coal, building construction, cement production, stripping of open pit mining, crushing, mineral processing and screening. This not only endangers human health and causes occupational diseases, but also accelerates mechanical wear and shortens the service life of precision instruments. What is even more frightening is that it is explosive under certain conditions.
In order to protect the health and life safety of workers, it is necessary to detect and control production dust. This requires the installation of corresponding PM2.5 sensors in the working environment to detect the environment to ensure that excessive dust is not inhaled.
The above are the specific applications of indoor pm2 5 sensor in fresh air systems, portable air quality detectors, air purifiers, industrial labor production dust environment monitoring and other places.
