Product Specification

MPM20 series dust sensor is a self-priming infrared dust sensor, which adopts the principle of infrared light scattering and has strong stability and consistency. It can automatically attract the external atmosphere, and the built-in heater can automatically intake air without adding an air pump. PM2.5 with lower inertia will float halfway, which is convenient for photoelectric sensor detection. The absolute number of particles per unit volume can be detected by using the same principle as particle calculator.
