Mobile air quality monitoring station - a solution for better pollution control

The paper presents the design of a mobile air quality monitoring station. Its mobility is defined by a lightweight and compact structure, allowing easy transportation and use without additional equipment. To enhance user convenience, a system for storing and analysing the collected data was implemented on an internet server, connected to a web application. The device includes a PM1.0/PM2.5/PM10 sensor, a barometer and hygrometer both with built-in temperature sensors, and two gas sensors. A GPS module provides precise location data, and a GSM module enables wireless transmission of results. The system is powered by Li-Ion batteries, with extended operation time thanks to a photovoltaic panel. The system was tested by comparing its measurements with air quality data from airly.eu, ensuring time and location consistency. The comparison confirmed the device’s accuracy while further tests in mobile mode, i.e., walking, cycling, and driving showed that the system’s mobility increases the number of measurement points, enhancing local air pollution monitoring. Mobile stations could be beneficial, especially in areas with a low density of monitoring stations, e.g. by using vehicles on fixed routes, such as public transport. This would allow effective air quality control and localization of point-source pollution.
