Fine particulate matter, also known as fine particles, fine particles, PM2.5 .Fine particulate matter refers to particles in ambient air whose aerodynamic equivalent diameter is less than 2.5 microns.It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious air pollution.The PM2.5 sensor is a digital general particulate matterconcentration sensor, which can be used to obtain the number of suspended particulate matter in the air of 0.3-10 microns per unit volume, namely the concentration of particulate matter, and output in the form of digital interface. Meanwhile, the mass data of each particle can also be output.The sensor can be embedded into various instruments or environmental
improvement equipment related to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.
