Abstract : This thesis takes place in the context of "smart cities", where the information processing improves the quality of life. It studies the perception of the environment and especially the perception of air pollution in the city using sensors on bikes. The first chapter introduces the technical and scientific challenges in terms of information collection and modeling applied to aerology. The second chapter presents the design of a fleet of mobile instruments for measuring air pollution. We characterize the shape of the sensor network needed for modeling, on the one hand using the literature and on the other hand using a simulation. The third chapter deals with the development of such an instrument. We have built our instrument around a semiconductor metal oxide micro-sensor (MOx sensor) of NO2 and CO, the MiCS-4514, and evaluated its performance in controlled environments. The fourth chapter presents the two deployments of this instrument in the city of Toulouse in France, first with a bicycle rental association and then with bikers from our laboratory, and the dataset collected. Finally, we estimate the pollution levels in NO2 and CO in the city
