This module makes use of the precept of optical LASER gentle scattering to measure the focus of particulate matter (PM2.5 and PM10) within the air. It consists of a LASER diode, a photodiode, a microcontroller, a low-noise amplifier and a suction fan.
The suctioned air passes by way of the detection chamber, the place the LASER gentle placing the suspended mud particles is scattered in all instructions and trans
