Air Quality Sensor with High Sensitivity to Amine and Sulfur Odors

TGS 2603 – for detection of Odor and Air Contaminants

The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor’s conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
