This 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 a digital interface can output quality data 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.
