Environmental Sensor – a Multifunction sensor – for the accurate measurement of environmental parameter humidity – temperature – volatile organic compounds (VOCs), oxidizing gases (NOx and O3) etc.
End customers receive reliable air quality and health and comfort benefit – based on measured data from sensor.


  • Humidity sensing: RH accuracy ±4.5%
  • Temperature sensing: T accuracy ±0.45°C
  • Particulate matter sensing:
Mass concentration precision for PM1 and PM2.5: ±5 μg/m3 AND 5% m.v.
