This paper presents a study of temperature modulation for tin-oxide gas sensor. The main objective of this work is to perform temperature modulation experimental setup for tin oxide gas sensors in order to improve the selectivity of the sensor array and to virtually increase the number of sensors. Typically, tin oxide sensors operate by heating at a(More)

Gas recognition is a new emerging research area with many civil, military, and industrial applications. The success of any gas recognition system depends on its computational complexity and its robustness. In this work, we propose a new low-complexity recognition method which is tested and successfully validated for tin-oxide gas sensor array chip. The(More)
The purpose of this paper is the study of the robustness of a new low complexity recognition method based on the measurement issued from an on chip 4times4 Tin oxide gas sensor array. The recognition system is based on a vector angle similarity measure between the query gas and the representatives of the different gas classes. The latter are obtained using(More)
