Application of Thermistors to STM32 Experimental Teaching
To minimize temperature measurement errors,this paper outlines a comprehensive approach that involves measuring the resist-ance values of thermistors at standard temperatures,by designing a hardware circuit and selecting an appropriate mathematical model for temperature measurement.Experimental results demonstrate that by constructing a precise measurement circuit and adopting an R-T(re-sistance-temperature)mathematical model,the temperature measurement accuracy is significantly improved,with the temperature error reduced to 0.175 K.Furthermore,the course experiment is group-based,fostering a collaborative learning environment.Through this innovative experiment,students can not only master the development process of temperature acquisition but also cultivate their innovative thinking,hands-on skills,and teamwork capabilities.This experience enhances their learning confidence and provides valuable insights into real-world industrial production processes.
