Claim 19:
20. The calibration method as claimed in claim 19, wherein
the first environmental sensor is a humidity sensor, the first environmental state is relative humidity, and the sensed first environmental state value and the calibrated first environmental state value are relative humidity values,
the second environmental sensor is a gas sensor, the second environmental state is gas concentration, and the sensed second environmental state value and the calibrated second environmental state value are gas-concentration values, and
the step of performing the calculation using the calibrated first environmental state value to calibrate the sensed second environmental state value and generate the calibrated second environmental state value comprises:
by the processing circuit, performing a calculation using the second sensed temperature value and the calibrated first environmental state value to compensate for a baseline resistance value of the second environmental sensor; and
by the processing circuit, performing a calculation using the compensated baseline resistance value to calibrate the sensed second environmental state value and generate the calibrated second environmental state value.
