AUTOMATIC CALIBRATION SYSTEM AND METHOD FOR GAS SENSOR

摘要

Disclosed is an automatic calibration method for a gas sensor. This method includes steps of acquiring a plurality of intermediate calibration data with different ranges by using gas samples with different concentrations; a step of extracting final calibration data from the plurality of calibration data; and a step of calibrating a gas sensor output with the final calibration data. The final calibration data extraction step is performed by extracting the median value of the intersection part of the plurality of intermediate calibration data.
