Abstract
A gas sensor includes a sensing element of a material including metal oxide and is sensitive to a target gas and to a recalibration gas different from the target gas. For recalibrating the gas sensor, a resistance of the sensing element is measured as an updated recalibration gas baseline resistance in a recalibration environment showing a recalibration gas baseline concentration.
