According to the different requirements of the people the design for the main implementing a clock/calendar can be displayed normal collecting personal ambient temperature with the timing alarm of the multi-function electronic clock Through access toa lot of paring and analysising the development technology of the electron clock the design determines to use the MCU technology to realize the multi-functional electron clock. This design application AT89C51 asa core chips 7 LED digital displaying using DS1302 real-time clock chip plete the basic function of the clock/calendar. At the same time the design use of DS18B20 temperature sensors to collect the environmental temperature. The method has the advantage of being simple circuit reliable performance good real-time high precision of the time and temperature cost-effective to develop more easily. Key words: Electronic cloc
