Air quality sensor module-Nowadays, the country pays more and more attention to the monitoring of particulate matter. What is often heard is pm2.5 and pm10. Then, what is pm2.5? What is pm10? What is the difference between them? Let’s take a brief look today. PM2.5 refers to particles with an aerodynamic equivalent diameter of 2.5 microns or less.
It can be suspended in the air for a long time. If the concentration of PM2.5 in the air is very high, it proves that the air pollution situation is serious. It has a great impact on the human body and the quality of the atmospheric environment. PM10 is also a kind of inhalable particulate matter.
The smaller the diameter, the deeper it enters the respiratory tract, and the greater the impact. The main source of particulate matter is the direct emission of pollution sources such as chimneys and vehicles, and the other part comes from nitrogen oxides in the air.
The fine particles formed by the interaction of volatile organic compounds, sulfur oxides and other compounds. Inhalable particles usually come from motor vehicles running on unpaved or cement roads, the crushing and grinding process of materials, and those raised by wind. dust.
As long as the damage of this kind of particulate matter to people is to harm the respiratory system and cause a burden on the lungs, it is also easy to cause respiratory diseases, especially those who are born with the respiratory system or suffer from asthma and other respiratory diseases.
Therefore, in daily life, we must pay attention to air pollution, air quality monitoring and air environment monitoring.
Air quality sensor module-The hazards of particulate matter should not be underestimated, so we must pay special attention to the atmospheric micro-station independently developed by Jingxuntong to measure PM2.5, PM10, sulfur dioxide, nitrogen oxides, ozone, and carbon monoxide in the atmosphere in real time.
It is suitable for online real-time monitoring of airport environment, atmospheric environment air quality and other fields. The atmospheric micro station adopts a new design method and big data automatic calibration function, which overcomes the shortcomings of traditional electrochemical sensors and can better monitor the atmospheric conditions. The large LED screen makes the reading observation more simple and convenient. It's clear at a glance.
