This study describes a portable system based on mimicking the mammalian olfactory mechanism (electronic nose), that can sense and identify chemical vapors by automated odor recognition. The electronic nose developed in this research consists of an array of tin oxide sensors, with each sensor in the array giving a different electrical response for a particular target vapor introduced into the sensing chamber. The combined output from the sensor array forms a fingerprint, or signature, that is… CONTINUE READING
