Design of High Precision Temperature Sensor Based on Platinum Resistance

Abstract:

for Pt100 platinum resistance temperature measurement system has low accuracy, duplicate hardware circuit design and other issues, the articles design a high-precision temperature measurement system with Pt100 platinum resistance. With Pt100 temperature sensor, article takes STM32F103 as the control center through filtering, amplification and other signal conditioning circuit and a method of combining software look-up table to compensate the nonlinear compensation, thus achieving high-precision temperature measurement. Research results show that the system has a measurement accuracy high stability, scalability, and other characteristics.
