APM10 Laser Particle Sensor Digital Output Small Size Stronger Anti Interference Performance
APM10 Laser Particle Sensor Digital Output Small Size Stronger Anti Interference Performance
APM10 contains a laser emitting element and a light detecting element. The two elements are placed in a cross-shaped manner inside the housing. The light detecting element collects scattered light intensity in real time. When air flows through the sensor cavity, the particles in the cavity air cause laser scattering. The light detecting element collects the change in scattered light intensity. The microprocessor calculates the equivalent particle size of the particles and the number of particles of different sizes per unit volume based on the Mie (MIE) theory.
