Air Quality Monitoring System Inside and Outside a Vehicle

This paper presents the implementation of a system capable of monitoring the air quality from outside and inside the vehicle in which it is installed, displaying the information to the user through two screens and alerting him in case the level of air pollution is high. Also, the presented system records the latitude and longitude coordinates at which the measurements of the air quality parameters are made in order to display on a map the degree of air pollution in different areas travelled by the user. The data collected by the system are mainly related to the emissions released by motor vehicles that use thermal engines, however, common data such as carbon dioxide (CO2), temperature, humidity and atmospheric pressure are also monitored. The collected parameters related to the emissions released by vehicles are dust particles in the air (PM1.0, PM2.5, PM10), carbon monoxide (CO), total volatile compounds in the air (tVOC) and methane (CH4). Thus, the system can bring additional information both to the driver who is alerted immediately about the level of air pollution, and to society, which will have an overview of the air quality, on the widest possible area of road infrastructure, displayed on a map easy to access and understand.
