Panasonic Industry SN-GCJA5 Particulate Matter (PM) Sensor

Based on laser scattering technology, the sensor detects particulate pollution in air

Panasonic Industry has introduced a Particulate Matter (PM) sensor which reliably detects smoke, dust and other unwanted pollutants in the air in homes, offices, factories, and any other indoor environment.

 

Based on a laser scattering measurement technique, the SN-GCJA5 sensor guarantees the detection of PM2.5, PM10 and PM1 particulates, and so can be used in ventilation and building-automation systems which protect human occupants from breathing in ultra-fine airborne pollutants.

 

The laser measurement technique offers several benefits, giving the SN-GCJA5 advantages such as:

  • Small size
  • Measurement of particulate matter concentrations which are accurate to ±10%
  • High sensitivity
  • Quick response
  • Stable performance supported by the sensor’s auto-calibration function
  • Special air pathway which minimizes dust accumulation inside the sensor

The sensor uses a laser diode emitter and an integrated photodiode which detects the scattered light reflected from particles floating in the air. A processor inside the sensor analyzes the wave profile of the signals from the photodiode. From this it calculates a mass-density measurement in μg/m3 supplied to the host via an I2C or UART interface.

 

The SN-GCJA5 sensor is housed in a 37mm x 37mm x 12mm surface-mount package.
