Category: Gas and Dust Sensor

The sensing element comprises a metal oxide semiconductor layer formed on the alumina substrate of a sensing chip together with an integrated heater. In the presence of detectable gas, sensor conductivity increases depending on 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. The TGS2602 has high sensitivity to low concentrations of odorous gases such as ammonia and H2S generated from waste materials in office and home
environments. The sensor also has a high sensitivity to low concentrations of VOCs such as toluene emitted from wood finishing and construction products.

Note: For more technical details go through Datasheet in the attachment section
