1. Introduction
Dust and smoke sensor, usually used to detect the concentration of dust, smoke and other particulate matter in the environment. When dust and smoke particles pass through the detection area in the air, the light will change due to scattering and blocking by the particles, and the sensor will convert the light signal into an electrical signal to reflect the concentration of particles.
