Abstract The main causes of a sharp change in the ecological state of the environment are considered herein. The use of modern nanomaterials to solve the problems of creating the required systems for monitoring and controlling the anthropogenic effect of humans on the environment, the use of plasma technologies for the formation of the working area, the frame and the diffusion barrier of the sensor are considered. So the use of plasma in the processes of processing and formation allowed reducing the total growth time of carbon nanoscale structures to 21 minutes. To improve the geometric parameters of carbon structures, the use of V, Cr, and Al sublayers was considered. At the end of this experimental work, the layout of the structure was formed and the laboratory and technological instruction for manufacturing a high-tech selective gas analyzer with a sensitive element based on an array of carbon nanostructures was issued. Analyzed are the distinctive features of the resulting model of high-tech gas analyzer. For testing the device under normal conditions, a specialized test chamber was used at a pressure of 760 Torr and a chamber temperature of 300 K. According to the results of an experimental series of studies, it was found that the generated utility model of the analyzer has characteristics of sensitivity to nitrogen oxide molecules and ammonia, ethanol and water vapor. Demonstrated are the corresponding current-voltage characteristics for various gas media, as well as the dependence of the discharge current on different gas concentrations. It was obtained that the breakdown voltage of the analyzer being formed does not exceed 10 V. The obtained results have shown the prospects of using carbon nanostructures as the basis for the formation of a gas analyzer with a high degree of sensitivity and selectivity to gas mixtures.
