The project Green Watch/Citypulse aims at multiplying by 1000 the number of environmental sensors in the city, while encouraging people’s implication in measuring environmental indices, thus associating them directly to building a sustainable city.

The green watch comprizes a watch and two environmental sensors (ozone, noise). Data are regularly broadcasted via a mobile phone to an open platform called Citypulse which receives, stores and makes measure data available and anonymous. Data can then be used freely in order to be shown on maps, used in models.

30 prototypes of the green watch was tested in May 2009 by residents of the 2nd arrondissement of Paris (Digital District) and also during Futur en Seine, by highschool students of Montreuil (Maison Populaire), by researchers in the Cité des Sciences et de l’Industrie and by visitors of the wikiplaza, place de la Bastille.
