小二、Times New Roman、加粗、AbstractThis paper introduces a kind of temperature measurement instrumentation based on MSP430 microcontroller, the temperature measurement sensor DS18B20 as the system core adopts serial munication with the micro processor. The system uses micro processor MSP430F1121A controlling DS18B20 in order to get the temperature data, which is displayed on the LED. The whole design includes two parts: micro processor MSP430F1121A and the temperature measurement sensor DS18B20, the MSP430 series have ultralow consumption and high integration, and the temperature measurement sensor only needs one pin to achieve the da
