Claim 22:
23. The calibration method as claimed in claim 19, 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 comprises:
applying a first atmospheric pressure to the sensing device;
when the first atmospheric pressure is applied to the sensing device and the temperature sensor operates and obtains the first sensed temperature value, driving the pressure detector to sense pressure and generating a first pressure output value by the processing circuit;
when the first 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 sense pressure and generating a second 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, and the second pressure output value to obtain a first output offset calibration parameter among the at least one temperature calibration parameters.
