AM1002 Integrated IAQ Sensor is an indoor air quality sensor that measures particle concentration, VOC concentration, temperature and relative humidity. This makes it useful as an all-in-one solution for measuring IAQ.

Particle concentration is measured by a laser particle sensor which uses the light scattering principle. The sensor measures and calculates the suspended particles and outputs the particle mass concentration μg/m3 directly.

The VOC sensor is MOX type, which has extremely high sensitivity to various kinds of organic volatile gases such as formaldehyde, benzene, ethanol, formic acid, nicotine and some inorganic gas like carbon monoxide, ammonia, hydrogen.


  • Three-Channel Output - PM1.0, PM2.5, PM10
  • Auto Particle Identification allows the sensor to "switch" between calibration algorithms based on changing application needs
  • Matrix calibration provides high accuracy throughout the working temperature and measurement range
  • Constant speed fan and constant power diode maintain measurement accuracy and stability


AM1002 - IAQ Sensor - integrates particle concentration, VOC concentration, temperature and relative humidity measurement in a single package.
