Abstract
A gas sensing device that includes a (a) gas reactive element that has a gas dependent temperature parameter; and (b) a semiconductor temperature sensing element that is spaced apart from the gas reactive element and is configured to sense radiation emitted from the gas reactive element and generate detection signals that are responsive to a temperature of the gas reactive element; wherein the gas reactive element and the semiconductor temperature sensing element are of microscopic scale.
