A tiny, streetlight-mounted sensor tracks urban air pollution via nitrogen dioxide levels.
Developed by a team from Chalmers University, the nanosensor can detect even low levels of nitrogen dioxide in the air by measuring the changes in wavelengths when the metal particles are illuminated. The technology can work with other airborne gasses, and was tuned specifically to detect NO2. The small sensors are also cheap and affordable, and can be installed in existing streetlights.
