Air Quality Meters PMS7003. PM2.5 Sensor Module Built-in Fan. NodeMCU It's not a finished productPrinciple: this sensor uses the principle of La Ser scattering, i. e. the La Ser is irradiated to suspended particles in the air to create scattering, and at the same time the scattered light is collected at a certain angle to maintain the curve of the scattered light over time. The microprocessor uses an algorithm based on the MIE theories to obtain the equivalent particle size of the particles and the number of particles of different sizes per unit
