超低功耗电子温度计

Ultra low power electronic thermometer

该超低功耗电子温度计以低功耗微控制器(MSP430F2174)为核心,基于IAREW编制软件系统,结合段式液晶显示(LCD)、必要的外围电路,能够通过温度传感器测量并显示被测量点温度。系统由温度传感器、数据处理(MSP430F2174)、键控液晶显示、时钟、串口通信等模块构成。能够根据键盘输入完成相应的功能,由LCD显示系统状态信息,同时,可以通过串口与计算机通信,作为远程操作模块。为满足超低功耗的要求,在设计时均采用低功耗元器件,实现了温度和时间测量显示,并进行了扩展(报警、查询、串口通信等)。

The ultra-low-power electronic thermometer consists of low-power Microcontroller （MSP430） as the coreemploying IAR EW, with pattern Liquid Crystal Display（LCD） and necessary peripheral circuit, through a temperature sensor that can measure and accurate temperature. The building blocks of the system involve temperature sensors, MSP430, keyboard control and liquid crystal display, a clock, serial port , and other modules According to the keyboard input , the system can complete the corresponding functions and display system status using the LCD. Moreover, through the serial port the system can communicate with computer and complete remote operation. To achieve ultra-low-power requirements, low-power components are used in the design .The system achieves the basic and additinal functions , and some expansion （alarm, query, serial port communication, etc.）.
