Paper Abstract

In this work, an identification system based on an array of semiconductor tin dioxide gas sensors has been developed. This system has proven a good success rate in the discrimination of carbon dioxide, forane or their mixtures without a sensor dedicated to carbon dioxide. After a characterization of the five sensor array, pre-treatment was tested on the collected data to select the well representing parameters. Then the information contained in the resulting look-up table was analyzed with PCA, but no significant result was observed. Discriminant factorial analysis was then used and has shown a better separation of the different clusters and unknown data were taken to validate the classification. So our results show that a reliable system can be designed using non-dedicated chemical semiconductor gas sensor.
