lnfrared Particulate Matter Sensor
The MPM20-AH series infrared PM sensor is a self-priming infrared PM sensor based on the principle of infrared light scattering. Its light source is an infrared LED light source. The LED emits light and produces reflected light when it encounters dust. Photosensitive detectors detect reflected light. Strong, determine the dust concentration based on the size of the pulse signal. The MPM20-AH series has a built-in heater and can achieve automatic air intake without the need for an air pump. PM2.5 with smaller inertia will be semi-floating, making it easier for photoelectric sensors to detect it. It uses the same principles as the particle calculator to detect the absolute number of particles per unit volume.
