Abstract
In this paper, the actual research for the background, a detailed analysis of the current status of temperature acquisition system and the current taken by the program's strengths and weaknesses, the company introduced the production of single-DALLAS-bus digital temperature sensor DS 18B20 features an analysis of timing of its work, and in accordance with its characteristics, with a simple interface with the formation of a single-chip temperature measurement system, through the keyboard and digital tube LED display on the system control and display. DS18B20 and give with AT89C51 single-chip temperature measurement system consisting of the application circuit and reference procedures. DS18B20 using the single bus structure, less occupied port system is very suitable temperature long-range multi-point detection system. Practice tests show that the temperature acquisition system and the device compared to traditional analog sensors, the system more accurate and more r
