ABSTRACT
This paper presents the development of a method for improving the accuracy of temperature measurement using a thermoresistive sensor. Thermistors are widely used semiconductor components that serve as temperature sensors. However, various parasitic factors—such as noise interference, hysteresis, and inherent nonlinearity—introduce significant measurement inaccuracies. The proposed method combines hardware calibration of the thermoresistive sensor with software-based correction of the measured data. Specifically, the approach involves error estimation and compensation through an exponential equation with three constants, determined via three-point calibration of the sensor. The results demonstrate that integrating hardware calibration with software corrections leads to a substantial improvement in measurement accuracy.
