Claim 23:
24. The calibration method as claimed in claim 23, wherein the step of obtaining the at least one temperature calibration parameter of the pressure sensor according to the first sensed temperature value and the second sensed temperature value by the processing circuit further comprises:
applying a second atmospheric pressure to the sensing device;
when the sensing device is applied by the second atmospheric pressure and the temperature sensor operates and obtains the first sensed temperature value, driving the pressure detector to detect pressure and generating a third pressure output value by the processing circuit;
when the second atmospheric pressure is applied to the sensing device and the temperature sensor operates and obtains the second sensed temperature value, driving the pressure detector to detect pressure and generating a fourth pressure output value by the processing circuit; and
by the processing circuit, performing a calculation using the first sensed temperature value, the second sensed temperature value, the first pressure output value, the second pressure output value, the third pressure output value, and the fourth pressure output value to obtain a first output gain calibration parameter among the at least one temperature calibration parameter.
