* Required Fields



The Air Quality Bricklet can measure

  • IAQ (indoor air quality) index,
  • Air pressure in mbar,
  • Humidity in %RH and
  • Temperature in °C.

The IAQ index is a measurement for the quality of air. To calculate the IAQ index the Bricklet detects ethane, isoprene (2-methylbuta-1,3-diene), ethanol, acetone and carbon monoxide (often called VOC, volatile organic components) by adsorption. These gas measurements are combined with the measurements of air pressure, humidity and temperature to calculate the final IAQ index.

The IAQ index has a range of 0-500:

IAQ index scale

Typical applications for this Bricklet are the monitoring of air quality, environmental statistics, home automation and similar.

The Air Quality Bricklet has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.

* This is the temperature at the exact position of the sensor. If the Bricklet is used inside of an enclosure, the air around the Bricklet may heat up more than the ambient air. The Bricklet does have API to calibrate this kind of offset.

Calibration of the temperature value is recommended, since the temperature value is used to compensate the IAQ index and humidity values.
