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 in the early 1970s and are still produced today by Figaro Inc., Japan. The Taguchi gas ...
