DFRobot Gravity PM2.5 Air Quality Sensor

DFRobot Gravity PM2.5 Air Quality Sensor measures particulate matter like PM2.5, PM1.0, PM10. It used the Gravity interface and works well with most main controllers. The sensor is based on the principle of laser scattering to employ a digital universal particle sensor that can continuously collect and calculate the number of suspended particles of different sizes in the air per unit volume.
