In the presence of the gas to detect, sensor conductivity increases according to 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.
The TGS816 is sensitive to a wide range of gases and the ceramic base make possible for the sensor to withstand severe environments up to 200°C.
The sensor has high sensitivity to methane, propane, and butane, making it ideal for natural gas and LPG monitoring.
