Аnnotation: A methodology variant for PM2.5 and PM10 particles mass concentration observation based on the Arduino UNO board and the Sensirion SPS30 laser sensor has been developed. The measuring system built according to the technique was used in the framework of a field experiment, as well as in continuous observation at a stationary point - the Moscow Geophysical Monitoring Center, IDG RAS. Examples of variations in the observed characteristics are given, which indicate the possibility of using the instrumental system in addition to those already existing devices when observing the geophysical environment. Continuous monitoring of the microparticles concentrations at the Geophysical Monitoring Center will make it possible not only to assess the megalopolis atmospheric pollution degree, but also to highlight certain trends, frequency and patterns. Such monitoring will also allow us to reveal the contribution of various sources to the increase in the microparticles concentration, as well as the effect of pollution on different geophysical fields.
