The GAIA air quality monitor uses laser particle sensors to measure in real-time PM2.5 and PM10 particle pollution, which is one of the most harmful air pollutants.

It is very easy to set up: It only requires a WIFI access point and a USB compatible power supply. Once connected, your real time air pollution levels are instantaneously available in on our maps.
