Description: The sensing element of gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. 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. The TGS 813 has high sensitivity to methane, propane, and butane, making it ideal for natural gas and LPG monitoring. The
