• ABSTRACT: The control of gas pollution is of utmost importance to environment protection and to ensuring healthy and safe working conditions. Modern development of industry, farming, transport is related to increasing the volume of emissions released in air and hence to the necessity of developing suitable technologies, equipment and filtering facilities for decreasing the emission of harmful substances and gases in the atmosphere. Air monitoring is also of great importance in order to prevent gas pollution which can spread over large territories for a short time. The present paper presents a system for control of gas pollution with: carbon dioxide, carbonic oxide, smoke, hydrogen, ammonia, nitric dioxide, ozone, hydrogen sulphide, methane, ethanol, hydrogen and volatile organic compositions (VOCs), as well as measurement of temperature and relative humidity. The system employs ZigBee technology and the user’s interface allows monitoring of the above-listed gas pollutants and also alarm functions when the respective norms have been exceeded.
