Assignee: INDUSTRIAL TECHNOLOGY RESEARCH INSTITUTE
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 21:
22. The calibration method as claimed in claim 19, wherein the first environmental sensor comprises a first sensing element and a first heater, and the second environmental sensor comprises a second sensing element and a second heater, the first heater and the second heater raise the temperature of the substrate, the temperature of the first sensing element, and the temperature of the second sensing element to rise, and the calibration method further comprises:
by the processing circuit, driving the first heater to operate; and
by the processing circuit, driving the first heater and the second heater to operate simultaneously,
wherein when the first heater operates and the second heater dose not operate, the temperature sensor operates to obtain the first sensed temperature value, and
wherein when the first heater and the second heater operate at the same time, the temperature sensor operates to obtain the second sensed temperature value.
