Anthropogenic factors are significant sources of environmental pollution. Particularly acute pollution is a problem for countries with rapid industrial development. The effects of environmental pollution are not a local but a global problem, as they threaten the entire Earth. Developing information systems for monitoring environmental pollution is a very important task. The study deals with the consideration of the hardware component of the data acquisition subsystem of this system. The environmental monitoring system receives data from many sensors that are connected to the network. The following three classes of sensor networks can be distinguished: static, public, and transport. Public networks are characterized by a higher density of sensors in the place of residence, and transport - along the transport routes. Inexpensive sensor technologies can significantly increase the density of air pollution data. This will improve impact assessments and increase community awareness of air pollution. Poor data quality remains a major challenge to the widespread adoption of low-cost sensor technologies. Unreliable data can mislead users and potentially have alarming consequences, such as reporting acceptable levels of air pollutants when they exceed the limits recognized as safe for human health. Bioelectronic noses used for monitoring water pollution are much more expensive and technologically sophisticated devices. It is advisable to use impactbased tools, such as biomarkers. The main problem with soil contamination research is to collect the need to collect soil samples and transport them to the laboratory.
