Title: CALIBRATING A GAS SENSOR
Abstract:
A gas sensor (1) comprises a sensing element (11) 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 (1), a resistance of the sensing element (11) is measured as an updated recalibration gas baseline resistance (RUpdBaseRG) in a recalibration environment (E3) showing a recalibration gas baseline concentration ( cBaseRG ).
