The electronic calendar in terms of hardware as the main control mainly STC89C52 microcontroller core, provided by the DS1302 clock chip clock, 1602LCD LCD display. STC89C52 microcontroller by Hongjing introduced, the power consumption, voltage can be selected 4 ~ 6V voltage power supply; DS1302 clock chip introduced in the United States DALLAS low-power real time clock chip, which can be year, month, day, week, hours, minutes and seconds time, but also has leap-year compensation, and other functions, and the DS1302s long life, small error; for digital electronic calendar using an intuitive digital display, digital display is used 1602LED LCD screen to display, you can also shows year, month, day, week, hours, minutes, seconds and other information. In addition, the electronic calendar is also a time calibration and other functions. In terms of software, including calendar, time to adjust procedures, display procedures. All programming is completed, the Keil software debugging, make sure that no problem, programmed into the microcontroller for testing.  This design mainly by the clock chip DS1302 temperature sensor to the microcontroller DS18B20 collect data for processing and then through the LCD1602 display, this thesis, the liquid crystal display LCD and clock chip DS1302, temperature sensor and microcontroller DS18B20 interconnection and communication between the hardware on Several hardware connection scheme for a detailed comparison of algorithms in software on the calendar have also been discussed.
