2、 Function Description
Sensors can be used to detect the concentration of particulate matter in the air around us, namely the PM2.5 and PM10 values. The working principle is developed based on the principle of light scattering: particles and molecules will scatter light under the irradiation of light, while absorbing some of the energy of light. When a parallel Monochromatic radiation is incident on the particle field to be measured, it is affected by the scattering and absorption around the particle, and the light intensity is attenuated.
