Classification: CPC G | IPC G

Claim 20:
21. The calibration method as claimed in claim 19, wherein the second environmental sensor comprises a second sensing element, the first environmental sensor comprises a first sensing element and a first heater, the first heater raises the temperature of the substrate, the temperature of the first sensing element, and the temperature of the second sensing element, and the calibration method further comprises:
by the processing circuit, driving the first heater to output a first power; and
by the processing circuit, driving the first heater to output a second power,
wherein when the first heater outputs the first power, the temperature sensor operates to obtain the first sensed temperature value, and
wherein when the first heater outputs the second power, the temperature sensor operates to obtain the second sensed temperature value.
