Laser Dust Sensor Dust Sensor PM2.5 DL0001 Description:

The laser dust sensor is a digital universal particle concentration sensor based on the principle of laser scattering. It can detect the concentration of suspended particulate matter of different particle sizes (including PM2.5) in the air. The sensor uses a laser diode as the light source, which illuminates suspended particles in the air to produce scattering, and uses a photoelectric detector to collect the scattered light. The collected scattered light generates a current signal due to the photoelectric effect. After amplification and processing by the circuit, the particle concentration value can be obtained. Then, through a microprocessor based on the MIE theory algorithm, it is converted into mass concentration (μg/m3) and output in a universal digital interface format.
