Description

technical field [0001] The invention relates to the field of air quality detection equipment, in particular to a simple vehicle-mounted haze meter. Background technique [0002] PM2.5 refers to particulate matter with a diameter less than or equal to 2.5 microns in the atmosphere, which has an important impact on air quality and visibility. Compared with atmospheric particulate matter with larger particle size, PM2.5 has a smaller particle size, larger area, and Strong, easy to be accompanied by toxic and harmful substances, and the residence time in the atmosphere is long, and the transportation distance is long, so it has a greater impact on human health and atmospheric environmental quality. The cost of PM2.5 detection technology in the prior art is high , although it can be detected in real time, it has not been applied to daily life such as automobiles. In view of the shortcomings of existing technologies, the inventor has developed a simple vehicle-mounted haze meter. ...
