"基于单片机的数字式温度计设计与实现：一线总线技术与DS18B20传感器应用"

The digital temperature sensor based on single-chip microcontroller is designed and developed in this document. With the advancement of technology, single-chip microcontroller technology has been applied in various fields. Compared with traditional temperature sensors, the digital temperature sensor based on single-chip microcontroller has advantages such as convenient reading, wide temperature measurement range, and digital temperature display output. This paper introduces a digital temperature sensor based on single-chip microcontroller control. The author carefully studies the one-wire bus technology developed by the American company Dallas and its communication protocol. This document first introduces the one-wire bus intelligent temperature sensor DS18B20 and the working principle of the single-chip microcontroller. Based on this, the corresponding hardware schematic and software program are designed to realize the temperature detection and display process. Finally, a summary of the problems encountered and the knowledge gained during the entire design process is provided. Keywords: one-wire bus, single-chip microcontroller, digital temperature sensor, DS18B20.
