Abstract：This thesis mainly introduces the design of microcontroller-based electronic calendar with temperature sensing and its implementation. The design chooses the STC90C516RD + microcontroller produced by STC Company as the control center. And the design also chooses DS18B20 to complete the temperature detection with the DALLAS Company’s digital thermometer as well as determines real time with the clock chip DS1302. Moreover, the design can present time, temperature and calendar by LCD12864 LCD. Buttons and alarm buzzers are equipped with active independent keys and 5V active buzzer and LED. It receives remote control signal by the infrared receiver. The design selects YF017 as voice broadcast chip, and 8Ω, 0.5W speakers for audio output. Except for the timing and temperature detection function, the design also adds the functions of presentation of lunar calendar and solar calendar automatical association, buttons to adjust the time, high and low temperature alarms, infrared remote control, voice broadcast and other extensions. The hardware of this design is simple, easy to operate, convenient and practical.
