Odor sensor is combination of a sensitive layer and a transducer. Nanocrystalline ITO thin film deposited over quartz crystal works as a sensitive layer, while quartz crystal works as a transducer. During operation of odor sensor, ITO layer sense the presence of test odor molecules, hence the totals mass on its surface will change, while the quartz crystal transducer converts the change in the mass into the change in the frequency. So the basic principle of operation of sensor is change in the frequency by change in concentration of odor or vapor molecules.
