Product Introduction
The MPM20 series dust sensor is a self-suction infrared dust sensor that uses the principle of infrared light scattering, with strong stability and consistency. It can automatically draw in external air, and the built-in heater can automatically suck in air without the need for an additional air pump. PM2.5 with lower inertia will float halfway, making it convenient for photoelectric sensors to detect. Using the same principle as particle counters, it can detect the absolute number of particles per unit volume.
