Application
Tips: What is the laser scattering principle for air quality sensors?
The laser light is scattered on the suspended particles in the air, and the scattered light is collected at a specific angle to obtain the curve of the scattered light intensity with time. The microprocessor then uses an algorithm based on Mie theory to derive the equivalent particle size of the particulate matter and the number of particles of different sizes per unit volume.
