FS00216 Laser Dust Sensor is a digital universal particle concentration sensor used for obtaining mass concentrations (μg/m³) of suspended particulate matter in air, including PM1.0, PM2.5, and PM10 as well as the number of 0.3, 0.5, 1.0, 2.5, 5.0, and 10um particles per unit volume. The sensor outputs data through a digital interface. It can be embedded in various instruments or environmental improvement devices related to the concentration of suspended particulate matter in air to provide timely and accurate concentration data.
