PULSE is a project funded by the European Community under the Horizon 2020 framework program, and aims to involve citizens in the management of public health and collective well-being. The Pulse @ PV app is aimed at the citizens of Pavia to promote responsible behavior taking into account the air quality of the city of Pavia. The app allows you to view the levels of PM 2.5, PM 10 and humidity detected by the network of sensors installed at various points in the city (public buildings and homes of voluntary citizens). We thank the Municipality of Pavia for their collaboration in the success of the project.
