Abstract
The present disclosure is directed to a selective multi-gas sensor device that detects when a high concentration level of a particular gas, such as methane, carbon monoxide, and/or ethanol, is present. The selective multi-gas sensor device detects and identifies a particular gas based on a ratio between a sensitivity of a gas sensitive material at a first temperature and a sensitivity of the gas sensitive material at a second temperature.
