Description:
APM10 Optical Dust Sensor is a digital particle detection sensor designed based on the principle of laser scattering, which can detect particle concentration in real-time, and is also called a PM2.5 sensor. APM10 can test particles with a particle size range of 0.3μm to 10μm.
It can provide a variety of different digital output interfaces. It has a boot-up self-calibration function and has good stability; it is small in size and easy to integrate.

Working Principle:
APM10 consists of a laser source and a light detector. As shown in Figure 2, the light detector collects scattered light intensity in real time. When the air flows through the duct, the particles inside the duct cause laser scattering. The light detector detects changes of the scattered light intensity. The subsequent acquisition circuit calculates the equivalent particle size and the number of particles of different sizes per unit volume based on the MIE theory.
