The LD19 is a high-precision particulate matter concentration sensor based on the Laser Mie Scattering theory. It can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume—namely the particulate matter concentration distribution—and convert this into mass concentration, outputting it via a universal digital interface. This sensor can be embedded in various instruments or environmental improvement equipment related to suspended particulate concentration to provide timely and accurate data.
