Chalmers University of Technology researchers have developed a nano-sensor to detect pollution that fits a standard streetlight. The optical sensor can detect low nitrogen dioxide levels using an optical event called a plasmon, and could be adapted to detect other gases. Researchers from the Chalmers Institute for Optical Engineering in Sweden used this new technology on a street light at Chalmers University. Chalmers is also collaborating with Sheffield University, which runs an air quality centre called the Urban Flows Observatory.

It has already been installed in a shopping centre in Sweden, where Chalmers is based, and is set to be rolled out on a railway tunnel construction route in the country.
