Abstract

A sensor calibration method comprises: providing a lot of sensors which are tested before production to obtain the summary pair-data set Di, classifying and dividing the summary pair-data set to obtain the typical pair-data sets Dj, and storing them in the computer; during production, testing the small number of pair-data of sensors to be delivered, inputting the small number of pair-data into the computer, and obtaining the closest typical pair-data set to the small number of pair-data through calculation, the typical pair-data set can be used as the predetermined pair-data of the sensor to be delivered, and the preset predetermined calibration function is no longer required, which improves the calibration efficiency of the sensor, reduces the production time, and improves the reliability of the sensor.
