7. A method for wireless calibration of a sensor, which uses the apparatus as claimed in any one of claims 1-6, wherein the method comprises:
step S1: obtaining a third parameter;
step S2: controlling the signal generation module to output a test signal according to the third parameter;
step S3: simultaneously applying the test signals to a standard sensor and a sensor to be calibrated;
step S4: collecting the first output signal and the second output signal;
step S5: comparing the first output signal with the second output signal to obtain a comparison result;
step S6; judging whether the comparison result is within a preset error range;
if so, the sensor to be calibrated is qualified, and the calibration is finished;
if not, obtaining a first modification parameter and a second modification parameter, obtaining the parameter modification instruction according to the first modification parameter and the second modification parameter, and modifying the parameter of the sensor to be calibrated according to the parameter modification instruction; steps S1-S6 are repeated.
