To meet the safety,municipal construction and other security need,a solar warning light is designed.With AT89C2051 used as the main controller and LM358 as the hysteresis comparator,the design of hardware and software is completed and a flashing alarm is achieved.The system is convenient in enlarging and secure in use and therefore has achieved good social benefits.With solar energy as the energy source and light dependent resistor as the sensitive component,the time and frequency of the flash are easy to adjust and good warming effect is therefore achieved effectively.

Key words: solar energy;warning light;comparator;single-chip microcomputer
