Abstract
A combustible gas sensor includes a first sensing element, which includes a catalyst and a heating element in operative connection with the catalyst to heat the catalyst above a temperature to combust gas analytes of interest, and electronic circuitry in operative connection with the heating element of the first sensing element to periodically cycle the first sensing element between a temperature above the temperature to combust the analytes of interest and a temperature at which the catalyst is substantially inactive to catalyze oxidative combustion of the analytes of interest. The electronic circuitry is adapted to determine a species of at least one of the gas analytes of interest from a first output of the combustible gas sensor during an ON time within a cycle duration. The electronic circuitry is further adapted to determine a concentration of the species of gas from a second output of the combustible gas sensor.
