Description: The system included four major components. They were the main controller, temperature measurement circuits, display circuits and control circuits. The system used AT89S52 SCM of ATMEL Company and DS1820 digital temperature transducer of the United States DALLAS company. First of all, the book introduced the performance and working principle of SCM AT89S52 simply, at the same time, the book gave a detailed introducing about the digital temperature transducer DS1820 in which the temperature measuring scope was between-55 and+125℃.This article key to the hardware, the software composition carried on the sub-item, the modulation has analyzed the design gradually and draw flow chart of each module. After the repeatedly simulation run, the debugging, and eventually realized the system functions.
The system can be applied in grain storage systems, building automation systems, air-conditioning systems, temperature testing and production process monitoring and other fields.
