Design of C8051F350-based Intelligent Pressure Sensor

【摘要】 In order to overcome the deficiencies of traditional pressure sensors,a kind of intelligent pressure sensors with temperature correction is designed.According to the intelligent sensor system of composition and range of applications,with fully taking into account the parameters of the connection between components of co-ordination,we chose a good usability,high reliability and low cost components composed of the entire measurement system,with controlling and dealing with in 80C51 microcontroller,the system had the temperature and pressure parameters with automatic measurement,amplification,A/D conversion,the weak signal locked amplification,as well as Phase-Sensitive Detection(PSD),common-mode signal rejection,the collected signal de-noising processing,cross-sensitivity of the decoupling and show the results.It also has a self-test,automatic temperature compensation and on-site communications and other functions.更多还原
