which reset gas sensor uses

Gas Sensor - an overview | ScienceDirect Topics

Resistive gas sensors are based upon monitoring a change in the electrical conductivity of a sensing material (primarily, non-stoichiometric semiconducting metal oxides like SnO 2, WO 3, ZnO and TiO 2) at high temperature (typically, 200–500 °C) in the presence of the gas. They are perhaps the earliest form of available gas sensor on the market. For example, Taguchi gas sensors (TGS) were commercialised …
