Want your own air quality monitoring station?

The GAIA air quality monitoring stations are using high-tech laser particle sensors to measure in real-time PM2.5 pollution, which is one of the most harmful air pollutants.

Very easy to set up, they only require a WIFI access point and a USB power supply. Once connected, air pollution levels are reported instantaneously and in real-time on our maps
