The application of PM2.5 sensors in different industries

Fine particles are also called PM2.5. Fine particles refer to particles with a diameter of air dynamic equivalent in the ambient air less than or equal to 2.5 microns. It can be suspended in the air for a long time. The higher the concentration in the air, the more severe the air pollution is. The impact of PM2.5 on the atmospheric environment and human health is also greater, which is the main murderer who leads to black lungs and haze days.

Fine particles are also called PM2.5. Fine particles refer to particles with a diameter of air dynamic equivalent in the ambient air less than or equal to 2.5 microns. It can be suspended in the air for a long time. The higher the concentration in the air, the more severe the air pollution is. The impact of PM2.5 on the atmospheric environment and human health is also greater, which is the main murderer who leads to black lungs and haze days.

With the advent of autumn and winter, some industrial and densely populated cities are prone to have haze weather due to air pollution. The haze is the air -soluble gel that combines dust in the air for a long time with water vapor. It affects the atmospheric environment and also affects people's respiratory tract health. In order to monitor the quality of air in time to reduce the damage to people, the PM2.5 sensor brings a comfortable living environment to people. Let’s see what areas of PM2.5 sensors can be applied to.

PM2.5 sensors are mainly suitable for air purifiers, ventilation, portable air quality detectors, and industrial labor production dust environment monitoring and other places.

Air purifier
Air purifiers is the main force of eliminating indoor pollutants. Removing indoor dust is the basic function of the air purifier. The PM2.5 sensor is undoubtedly the source of the air purifier to remove the dust. At present, most of the air purifiers on the market use laser PM2.5 dust sensor to detect the dust in the room.

Portable air quality detector
Now more and more people use the air detector, mainly because the air quality has attracted more attention in recent years. It can only see the haze, but it does not know what extent the pollution is. This will make people feel disturbed. The air detector can data the degree of air pollutants and make the data of air quality pollution visible. The PM2.5 sensor is also one of the core components of the air detector. The detection output signal of the PM2.5 sensor shows the real -time concentration of PM2.5 in the air.

Industrial labor production environment dust monitoring
In industrial production, there are always have small particles such as dust and PM2.5. Workers who stay in the environment of dust concentration for a long time will seriously affect health. For example, mining enterprises will produce a large amount of dust, which not only endangers human health, cause occupational diseases, but also accelerate mechanical wear, shortening the service life of precision instruments. And it will explosive under certain conditions. Dust is produced in various production processes of mining companies: such as drilling, blasting, digging and cutting, construction, cement production, open -air mining, crushing, mineral processing and screening. Production workers work in high -concentration dust environment for a long time, inhaling a large amount of fine dust, seriously endangering human health, causing occupational diseases such as coal lung disease, and coal lung disease. In order to protect the health of workers, it is necessary to detect and control product dust. The corresponding PM2.5 sensor needs to be installed in the working environment to detect the environment to ensure that it will not inhale excess dust.

Ventilation system
The most important function in the ventilation system is intelligent filtering the PM2.5 particles in the air. The dust particles in the air will follow the breath to enter the human respiratory tract, which is very harmful to human health. The higher the concentration of PM2.5 in the air, the more severe the pollution of the air. The PM2.5 sensor is the key to perceive the dust particles in the air.

ZH07 laser dust sensor

This PM2.5 laser dust sensor is a universal, small laser dust sensor module. The principle of Michael scattering can be used to detect the dust particles existing in the air. Through professional algorithms and calibration detection processes, this sensor has good consistency and stability. ZH07 also has serial port output and PWM output, easy to use, small volume, and easy to integrate.
