Design of Low Scale Pressure Sensor Intelligent System with Temperature Compensation Based on STM32

摘要

This article designs and implements a pressure sensor intelligent system with temperature compensation, which is based on STM32F103RCT6 microcontroller. The system is used to measure accurate small range signals of pressure sensor. Designing the functional circuit makes the output of the system digitized. Utilizing the improved BP neural network algorithm compensates the digital signal of the pressure sensor to ensure the accuracy of the pressure sensor. The repeated test shows that the intelligent system compensates the temperature drift of low scale pressure sensor effectively and ensures the property and the measurement accuracy of the pressure sensor.
