Temtop PM-900 Laser Particle Sensor measure PM1.0,PM2.5 and PM10Overview: PM 900 is a laser based particle sensor that uses the light scattering method to detect and count particles and calculate PM1. 0, PM2. 5, and PM10 concentrations in a given environment. The sensor features an imported processing chip and element. Signals are collected and processed by the microprocessor chip and then output in digital format. The sensor is ideal to detect the concentration of different particles precisely in real time.
