Based on the laser scattering principle, AUDIOWELL's self-developed laser dust sensor can detect the concentration of suspended particles (including PM2.5) of different particle sizes in the air, and is suitable for all kinds of air quality measurement and purification systems in the smart home.
The product uses a laser diode as a light source, irradiated on the suspended particles in the air to produce scattering, built-in photodetector to collect the scattered light, using the photoelectric effect to generate current signals, and then amplified and processed by the circuit, you can derive the concentration value of the particles; through the microprocessor based on the theory of the Mie (MIE) converted to the quality of the concentration, and the output in the form of a digital interface.
