Air Quality Sensors

A device that allows communities to see the air they breathe

Airly sensors measure the air quality in your immediate surroundings

Easy to install, our devices are calibrated and continuously verified to guarantee reliable information that can be viewed in real-time from your mobile or computer.

A small device that builds the big picture

By tracking all the key pollution markers; particulate matter (PM1, PM2.5, PM10), NO2, O3, SO2 and CO gases, you can see a complete and accurate picture of the air you breathe. Our online maps also integrate trustworthy data about key weather parameters such as temperature, humidity, air pressure and wind from the locations where our sensors are installed.


Sensors installed worldwide


Operating in countries all around the globe

How it works?

Air pollution sensors measure the particulates using the laser method. In the case of gas pollutants, our single device is able to measure two chemical compounds by electro-chemical method. Readings are taken from two cells installed in the gas module of the sensor. Each sensor has a special light diode that changes to clearly show the current air quality using a colour consistent with the CAQI scale.

  • CO, NO2, O3, SO2 – key gas pollutants that our sensors measure
  • GSM – protocol used for data transmission

Quality proven by extensive tests at Airlab-Airparif. Paris, France [Microsensors challenge 2019]
