An System Based On STM32 And Piezoresistive Air Pressure Sensor

EasyChair Preprint no. 4004

Abstract

Breath pressure is a very common measurement parameter of health intelligent products. In this paper, piezoresistive bridge air pressure sensor is used as data acquisition component. Using precision instrument amplifier and adjusting circuit amplifier as signal processing unit， STM32f103c8t6 control system is data processing unit. Optimize the circuit design of instrument amplifier, Overcome the weak signal and the temperature drift error and nonlinear error, Complete the hardware system design of respiratory pressure detection, amplification, control and display system.

Keyphrases: instrument amplifier, Piezoresistive bridge, sensor, STM32
