Gravity: Laser PM2.5 Air Quality Sensor For Arduino

PM2.5 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. The sensors can be embedded in a variety of concentrations of environment-related instruments suspended particulate matter in the air , to provide timely and accurate concentration data.
