The BrusSense team is formed by Matthias Stevens and Ellie D’Hondt, two young and ambitious researchers at the Vrije Universiteit Brussel’s Computer Science Department. It is a continuation and an extension of the NoiseTube project, which investigated participatory techniques for monitoring noise pollution. In particular we turned mobile phones into noise sensors, thus enabling each citizen to measure personal exposure in his or her everyday environment. A collective map of noise pollution is built up by automatic sharing of users’ geolocalized measures within the community. BrusSense will extend this approach towards atmospheric pollution as well as implement a case study in the Brussels Region, an urban area with pollution problems aplenty.
