For both human health and the environment, air pollution is a serious concern. However, available quality monitoring networks have important limitations, such as high implementation costs, limited portability, considerable operational complexity. In this context, unmanned aerial systems (UASs) are emerging useful technological alternative due to their ability cover large distances access areas that difficult or impossible for humans reach. This article presents development of an integrated platform combines system (UAS) with specialized sensors measure key parameters in relation quality, carbon monoxide (CO), ozone (O3), nitrogen dioxide (NO2). addition, web application called PTECA developed visualize data gathered by wireless sensor array real time. The incorporates allows real-time tracking UAS route measurement values during sample collection, employing LoRa communication protocol. solution represents low-cost mitigates some limitations traditional offering greater portability accessibility terms collection. Preliminary tests successfully demonstrate viability proposed controlled airspace using geofencing.
