  • What is the principle of particle sensors?

    Laser particle sensor can obtain the number and quality of suspended particles in the air per unit volume, which is called particulate matter concentration. Meanwhile, it can output as a digital interface. Based on the principle of laser scattering, when the air outside uniformly passes through the specially designed air duct, the laser light is scattered on the suspended particles in the air, and the information processing circuit converts the light intensity signal of the scattered light into a voltage...
