The development of gas recognition technique using multysensor system for air monitoring

Abstract

The development of gas recognition technique using multysensor system for air monitoring

Kravchenko E.I., Petrov V.V., Varezhnikov A.S.

  The problem of air quality control is relevant at the present time. There are a lot of different devices and methods of air monitoring. The promising devices for air monitoring are automated air monitoring systems functioning in real time regime. The basic part of such system is a chemical gas sensor. Gas sensors can be combined into the arrays or so called multisensory systems to increase their effectiveness. Sensor arrays using semiconductor sensors based on SiO2CuOx, SiO2SnOxCuOy, SnOxZrOy, silver-polyacrylonitrile thin films made at department of chemistry and ecology have been investigated in this work. As a result of sensors signals processing gas recognition technique has been developed. The recognition of ammonia, nitrogen dioxide, chlorine has been made.

Keywords: monitoring, massifs of sensors, semiconductor sensors of gases
