Abstract—Electronic Nose employs an array of gas sensors and has been widely used in many specific applications for the analysis of gas composition. In this study, electronic nose, integrating ten MQ gas sensors, is intended to model olfactory system which generally classifies smells based on ten basic categories namely: fragrant, sweet, woody/resinous, pungent, peppermint, decaying, chemical, citrus, fruity, and popcorn using artificial neural network as its pattern recognition algorithm. Initial results suggest that four (Pungent, Chemical, Peppermint, and Decaying) among the ten classifications are detectable by the sensors commercially available today while technology for classifying the remaining six is still under development. Meanwhile, results provided by this study affirm that electronic nose indeed displays a potential of modelling olfactory system.
