Substantial financial resources are required for the procurement, installa-tion, calibration, and maintenance of such measuring devices. For this reason, existing national and local air quality monitoring networks are not able to provi-de a high temporal and spatial resolution of measurement results. In the last decade, as a possible alternative to the conventional approach to air quality monitoring, real-time monitoring systems using low-cost sensors and sensor plat-forms have begun to be applied. This paper describes the basic characteristics of a portable air quality monitor PAQMAN 2020 based on low-cost sensors. Part of the results of comparative measurements of this device with the reference instru-ments is presented in the paper.
