Internet of Things (IoT) for Monitoring Air Pollutants with an Unmanned Aerial Vehicle (UAV) in a Smart City

Incorporating sensors for data acquisition to upload them afterwards to the internet is one of the applications of the internet of things (IoT). This research approaches IoT in an environmental way, concerning the air pollution and its measures as one of the biggest problems nowadays. Air pollution affects not only natural environment, but also human health. There are several ways for measuring air pollution through sensors integrated in fixed monitoring units, which are grounded in strategic city areas. These monitoring units have limited range of scope and height limitations as well. The paper presents a system for data acquisition, designed and incorporated into a UAV, which allows monitoring the pollutants criterion in air. Collected data is then sent to a ground station by radiofrequency, where the station processes the information and sends it to the Internet. The results are shown through a web page that can be displayed on any computer or mobile device. The actual proposal seeks to incorporate the technology into a smart city.
