We're launching the Bristol Clean Air Challenge with Sustrans on National Clean Air Day, Thursday 17 June. We want organisations and individuals to do their bit for clean air in the city by doing more journeys on foot, bike or by public transport.
Most countries around the world rely on government reference stations to monitor background air quality. Whilst very accurate, they are also very expensive and are normally fixed in position.
Low-cost sensor technology is key to realising the many commercial applications of passive air quality monitoring. Why, then has it not yet been adopted more widely?
