Abstract

Gas sensors usually exhibit lack of selectivity, require frequent calibration, exhibit drift of the response and a lot of factors, such as humidity or ambient temperature, influence their performance. Different approaches can be used to overcome this shortcomings. Building arrays of different sensors and usage of pattern recognition methods to analyze responses of elements in array is a popular approach. In this paper the approach of using a single sensor and special measurement techniques will be presented. Instead of increasing the number of sensors an additional information, needed to improve the properties of the sensor, is obtained from the response signal of a single sensor.
