Abstract: E-calen dar day time is a very wide range of tools,giving great conwenience to people, commonly found in various places. It can be used in visual digital display the dateand temperature information, at the same time ,It has the functions of timing and time calibration., but also a time-calibration and other functions. The core components of the electronic calendar is AT89C51 single chip, using DS18B20 temperature sensor is used to measure the temperature, the clock chip is used DS1302 chip, common cathode LED display. AT89C51 MCU is designed by Atmel company, the power consumption is very small; DS1302 clock chip is the United States DALLASs low-power real-time clock chip, has the leap year compensation and other functions, which can of the year, month, day, week, hour, minutes and seconds, and the error is small, long service life; DS18B20 temperature chip is a digital temperature sensor with a measurement accuracy high, a simple circuit to connect the characteristics of such sensors only need a data cable for data transmission; This display equipment of the design is chosen the Common cathode digital tube, which can display year, month, day, week, time, minutes and seconds and temperature, etc.
