Abstract:
An apparatus and method for detecting selected chemical compounds or elements is presented. A sensor array is exposed to one or more odors, for example. The outputs of the sensor constitute input to a pattern recognition system. Embodiments of the invention can also be trained for detecting odors in a soil column, for detecting odors associated with different varieties of food such as coffee beans, and for detecting odors associated with substantially any odorant.
