GS1001 Laser PM2.5 Dust Sensor
This sensor adopts the principle of laser scattering. When the air passes through the measuring cavity, the suspended particles in the air scatter the laser, the scattered laser light is collected at a specific angle, and the curve of the scattered light intensity over time is obtained. The microprocessor calculates the equivalent particle size of the particles and the number of particles of different sizes in the unit volume according to the MIE theory.
