The method to implement temperature compensation by software is discussed. The principle of software algorithm for high-accuracy tempera-ture compensation is expatiated,which provides a theoretical basis for temperature compensation by software. The experiment re-sults prove that the sensor output accuracy has been significantly improved by the high-accuracy temperature compensation algo-rithm.
