基于MS5611-01BA01的高精度气压和温度检测系统设计

气压和温度是实验室和工业上的重要参数，实时精确地测量这两个参数从而对实验室环境和工业生产环境进行控制具有重要意义。本设计采用超低功耗单片机MSP430F149，通过Ⅰ^2C接口控制MS5611—01BA气压传感器，并对气压和温度进行高精度测量，最后通过液晶显示屏将这两个测量值显示出来。系统中各个模块都是采用3．3V供电，并使用了MSP430F149单片机的低功耗模式，有效降低了整个系统的总功耗。实验结果及分析表明，该设计精度高、功耗低、稳定性好、可靠性高，适合于要求较高的实验室和工业生产中，并且扩展能力强，可以进行更多功能的开发。

Design of High Resolution Pressure and Temperature Measurement System Based on MS5611-01 BA01

Pressure and temperature are important parameters in laboratory and in industry. It is great significance to measure these two parameters real timely and accurately to control the environment of the laboratory and industrial production. This design uses the ultralow-power MCU MSP430FI49 by the I2C interface to control MS5611-01BA pressure sensor on high resolution pressure and temperature measurement. Finally, LCD will be used to display these two results. Each module of this design using the 3.3V supply voltage and the low-power operating modes of MSP430F149 make the total power consump- tion of the whole system very low. This design characterized by high resolution, low power consumption, good stability and high reliability is suitable for the laboratory and industrial production which is higher requirements. It can develope more functions for its good extended capability.
