Environmental monitoring stations are used to follow changes in air pollution level indoors or outdoors. In today’s cities these data play a central role in environmental monitoring of industrial and construction facilities to predict ecological situation and build recreational facilities. Technically, the most difficult task is to detect dust and black carbon particulate matter less than 10 µm in diameter (PM2.5 and PM10). These particles are harmful to human respiratory system and may cause severe respiratory diseases and even lung cancer when breathed in high concentration. Getting accurate data on air pollution in the monitored area is possible only if you use a distributed system made up of great number of sensitive detectors delivering data in real time mode. To top it off, each dust sensor has to provide unattended operation under different conditions and ensure easy installation on any type of surfaces, minimum maintenance and weather resistance (downpour, stormy wind, frost up to minus 40 °C). One of the challenges when performing the dust monitoring is the data accuracy decreasing with the long-term usage of the sensors. This effect is caused by the unavoidable clogging of filter and air duct of the sensor. Filter clogging, especially when speaking about problem areas, results in the need to provide regular sensor maintenance which requires high labor input when maintaining a large sensor system. Today’s market does not offer a ready-to-use solution able to solve the above described problems of sensor operation under severe Russian weather conditions. The main problem is low weather resistance of the optical dust sensors, that stop working even at slightly negative temperature. The market offers alternative solutions, such as portable environmental labs and stationary weather stations equipped with a great number of different measuring tools. However, their high cost, redundant functionality and big size do not allow using them to build a large city monitoring network. The absence of a ready-to-use solution in the market resulted in the need to develop our own air monitoring stations.
