Designing low-cost sensors for high-quality air pollution monitoring
Résumé
Particulate matter (PM) is highly toxic, especially small size particles reaching vital organs through blood. In Grenoble, the spatial distribution of PM is heterogeneous but only two official background stations monitor small size PM. Therefore, public exposure to PM is poorly estimated. A solution is to build easy to move low-cost measurement stations which can be deployed at various locations in the city. But the data quality of such stations must be characterized beforehand. We have developed a low-cost station (LCS) solution and compared data from LCS with that from an official reference station (Atmo Auvergne Rhône-Alpes) used by authorities.
