G5 PMS5003 Laser PM2.5 Sensor Accurately Detector Smog Serial Port High Precision
This sensor uses the principle of laser light scattering. That is, the laser illuminates the suspended particles in the air to generate scattering, and at the same time, the scattered light is collected at a certain angle to obtain a curve of the scattered light intensity with time. Furthermore, the microprocessor uses an algorithm based on the MIE theory to obtain the equivalent particle size of the particles and the number of particles of different particle sizes per unit volume.
