This paper introduced the function of Timing and Temperature Controlling Zymoscope, the characteristic and principle of the single bus digital temperature sensor DS1820. The paper applied to the single-chip-microcomputer AT89S52 to have designed a digital automatic device controlled by temperature, which is based on the DS18B20. It showed the hardware structure, control panel and software design of this device. The device has reached to the standard in all kinds of performances through practice and applied for the patent. It has been put into production.The effect of using is better and the performance is stable and trustiness.
