Breathe London

Citizens in London are provided with low-cost, easy-to-install sensors, so they can monitor air pollution in their local area. This is part of the citizen-science program, Breathe London, which besides collecting data aims to raise awareness about air pollution. The sensors will monitor particles (PM2.5) and nitrogen dioxide (NO2) using both solar and the electric grid. Small sensors are not as accurate as reference-grade analysers, but the sensor data will be combined with data from the reference network to ensure valid data. The project is run by the Environmental Research Group at Imperial College London, which has long and extensive experience in air pollution monitoring.
