"基于MSP430和DS18B20的数字温度计设计——大学毕业论文"

Abstract: The design of a digital thermometer based on the low-power MSP430 microcontroller is presented in this paper. The entire system controls the DS18B20 temperature sensor to read the temperature through the MSP430F149 microcontroller and displays the temperature on a digital tube. The temperature sensor DS18B20 communicates with the microcontroller through a serial port. The MSP430 series microcontroller has ultra-low power consumption and high peripheral integration. The DS18B20 only requires one port for data communication, making it easy to connect. Through multiple experiments, it has been proven that the test results of this system are consistent with the actual environmental temperature. In addition to its simple interface circuit, high measurement accuracy, small error, and high reliability, the system's low cost and low power consumption make it have a broader application prospect.
