基于AT89S52单片机的声光控制开关设计

摘要

An electronic switch which has the characteristic of simple circuit,energy saving,sound-light control was de-signed. AT89S52 microcontroller is used in the switch for programmable control. In combination with peripheral photoresistor, acoustic sensors and LED,the automatic control,hommization control and precisely delay control of the sound-light control lamp controller were realized,the hardware cost was reduced,the reliability and stability of the system was improved,the pur-pose of energy-saving was achieved,and the life of lamps was prolonged.%　　论述设计了一种电路简洁、节能节电、声光控工作的电子开关。利用AT89S52单片机进行可编程控制，结合外围光敏电阻、声敏元件、LED等，实现了声光控路灯控制器自动控制、人性化控制以及精确地延时时间控制；降低了生产硬件成本；提高了系统的可靠性和稳定性；达到了节电和节能的经济目的，延长了灯的使用寿命。
