Infrared PM Sensor
The MPM20-AH series is a self-priming infrared PM sensor that adopts the principle of infrared light scattering. Its light source is an infrared LED light. The LED emits light and produces reflected light when encountering dust. The photosensitive detector detects the intensity of the reflected light and determines the concentration of dust according to the size of the pulse signal.
The MPM20-AH series has a built-in heater and can realize automatic air intake without the need for an air pump. PM2.5 with lower inertia will float halfway to facilitate detection by the photoelectric sensor. It uses the same principle as the particle calculator to detect the absolute number of particles per unit volume.
