| Abstract: | The internal structure and timing control of new 1-Wire temperature sensor DS18B20 with a number of highperformance features are introduced. On this basis, the C8051F020 MCU processor combined DS18B20 constitutes a temperature measurement system. Its hardware composition and software design are introduced. The focus of software programming and the access to high-resolution are pointed out. Finally,actual temperature is acquired by the system in more stable environment. According to the data from PC serial by MFC programming, the figure is draw to prove temperature resolution of 0. 0625℃. The device is suitable for daily life of people, industrial production and scientific research in the field of temperature measurement. |
