Air Monitoring by Means of Electronic Nose

Abstract

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 multisensor systems to increase their effectiveness. Sensor arrays using semiconductor sensors based on SnOxZrOy thin films have been investigated in this work. The recognition of ammonia, nitrogen dioxide has been made.
