I. Product Name: Luftmy Laser Dust PM2.5 Sensor Module

II. Product Model: LD09

The LD09 PM2.5 laser dust sensor is a high-precision particulate matter concentration sensor based on Laser Mie Scattering Theory. It can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume, with a universal digital interface output. It can be embedded in various instruments or environmental improvement equipment related to the concentration of suspended particulate matter concentration in the air to provide timely and accurate concentration data.
