Claim 7:
8. The gas sensing device according to claim 1, wherein the gas sensing device comprises a further sensing unit for sensing a further target gas, the further sensing unit being configured for providing a further measurement signal based on a concentration of the further target gas in the environment of the gas sensing device, wherein the signal calibration unit is configured for determining the calibrated measurement value based on the measurement signal and the further measurement signal, and wherein the gas sensing device further comprises:
means for evaluating the further measurement signal so as to decide whether the further sensing unit is in a malfunctioning state, and
wherein the signal calibration unit is configured for, if the evaluation of the further measurement signal indicates, that the further sensing unit is in a malfunctioning state,
determining the calibrated measurement value independent of the further measurement signal, and/or
using, as the calibration model, a further calibration model which is independent of calibration data from test sensing units of the type of the further sensing unit.
