BOB-08891 - Gas Sensor Breakout Board
Laser dust sensor is a digital universal particle concentration sensor，it can be used to obtain the number of suspended particulate matter in a unit volume of air within 0.3 to 10 microns, namely the concentration of particulate matter, and output with digital interface, also can output quality data of per particle.
