SN-GCJA5 - Air purity sensor range: 0÷2000ug/m3 -10÷60°C

The sensor detects “PM (particle matters) in the air” by optical method.This sensor uses LD (laser diode) as light-emitting device and PD (photo diode) as lightreceiving device.The LD inside the sensor emits light to the air in a detection area. The PD inside the sensordetects scattering light which correlated to the actual floating particles in the air.A Microcomputer (MCU) inside the sensor analyzes the wave profile from PD by optimisticalgorithm, then output a converted mass-density (μg/m3) through I²C & UART interface
