Abstract

Solar multi-function LED clock is using solar powered. And it can detect temperature and illumination. It uses LED as display, has the characteristics of energy saving and durable use, and uses solar panels to make the whole clock system become green and environmentally. This design takes MCU AT89C51 as the control core, using solar panels to provide energy for the entire system, implements the basic function of the clock with the DS1302 clock chip, completes the check of the temperature and illumination of the multi-function clock by using the DS18B20 temperature sensor and the ON9658 illumination sensor, so that the control module can make timely adjustment and collection. Using LED digital tube as the display module of the clock, the control software is written in C language and simulated by Proteus software, so as to realize the simulation of the multi-function LED clock design of the solar energy. This design firstly summarizes the solar multi-function LED clock, and analyses the characteristics and development trend of the multi-function clock. Secondly, the overall structure design, hardware design and software design are completed according to the design requirements. Last but not least, debugging and simulation are carried out. The simulation results are basically consistent with the theoretical analysis results.
