Air Quality Sensor – PM2.5, PM10

By Boris Landoni on September 19, 2022

This module uses the principle of optical LASER light scattering to measure the concentration of particulate matter (PM2.5 and PM10) in the air. It consists of a LASER diode, a photodiode, a microcontroller, a low-noise amplifier and a suction fan.
The suctioned air passes through the detection chamber, where the LASER light striking the suspended dust particles is scattered in all directions and trans
