Abstract

Hydrogen content in the urban atmosphere is a new sensitive indicator of the environmental ecology. The complexity of determining this element due to low absolute concentrations and high volatility of this gas requires the development of specialized autonomous complexes for H₂ monitoring and challenge. We have developed a robotic complex based on a wireless data transmission network - wireless sensor network (WSN) technology and specialized hydrogen sensors developed by metal-insulator-semiconductor (MIS) structures.

The article presents the first data on monitoring in the Moscow region at two stations with high and low levels of atmospheric pollution. It is shown that the course of hydrogen is complementary and is determined by atmospheric parameters, but the difference in concentration levels in the center of Moscow and on its border is almost an order of magnitude. These data are compared with information on monitoring in other cities of the world - Paris, Helsinki, etc.
