working principle

ZH-JSQ100Dust particle counter sensorBy using the principle of single particle laser scattering, precise optical design and an air path designed based on fluid mechanics principles, particles in the sampled air are highly likely to pass through the beam in sequence, generating weak scattered light; Through precise optical signal receptionCollection deviceCollect scattered light and project it onto a high-sensitivity, high bandwidth photodetector. By identifying and analyzing the scattered pulses of each particle, the signal intensity corresponding to each particle is obtained; Obtain the particle size of each particle through a calibration program; After conversion and aerodynamic calibration, the number of particles is obtained.
