   In this article, we consider the possibility of using small-sized sensors on the territory of the Russian Federation to measure the concentrations of pollutants during observations of atmospheric air pollution. This issue is currently very relevant due to the high demand for information on the quality of atmospheric air of both the population and authorities. Due to this, gas analytical equipment is being developed and modernized, minimizing its size and becoming cheaper. The article describes various types of small-sized sensors, which include sensors with using electrochemical and semiconductor sensors, etc., schematic diagrams are presented, conclusions are drawn about the advantages and disadvantages of the described sensors.

   On the territory of Russia, the environmental monitoring network is not developed in all cities, and with the help of this type of sensors it could be expanded. However, now there is no regulatory framework on this issue and the concept of “small-sized sensor” in Russian legislation.

   After carrying out the analysis, it can be concluded that the use of the discussed sensors is currently possible within the framework of educational programs to popularize the issues of atmospheric air protection, as well as for research purposes, including a preliminary assessment of the quality of atmospheric air; designing/optimizing a network of observation posts; air quality monitoring in areas where there is no risk of exceeding the maximum permissible values. In this regard, the authors propose, first to introduce the concept of “small-sized sensor” and to determine the criteria and parameters based on which comparisons of this type of equipment should be made.

Keywords: atmospheric pollution, autonomous monitoring, small-sized sensors, electrochemical sensors, semiconductor sensors.
