摘 要

声光触摸控制照明灯开关，能自动控制白天开关、夜晚亮灯、人走灯灭。具有灵敏、低耗、性能稳定等特点。设计声光触摸控制延时开关,综合了声、光、触摸和延时控制。本文阐述了简单的声光触摸控制照明灯开关的制作。采用CD4011四二与非门芯片，驻极体传声器、光敏电阻、电容等作为基本元件。光敏电阻,驻极体传声器和触摸片三种传感器形成了声控、光控和触摸三种控制的电路。利用protel99se软件完成电路原理图的制作和PCB电路板的制作。开关制作完成后，测试结果实现了所要求的控制。

Abstract

Sound and light touch control lighting switches, automatic control can be switched during the day, night lighting, and eliminate people of lights. It’s feature is ensitive, low consumption, stable performance, ect. Design acousto-optic touch control delay switch which combine sound and light, touch and delay control. This paper expounds how to make a simple sound and light touch control lighting switch (DIY). It’s basic device is CD4011 42 sr chip, microphone, photoresistance, capacity, etc. photoconductive resistance, microphones and touch tablet three sensor formed sonic, ligh-activated and touch three control circuit. Use protel99se software circuit principle diagram production and PCB production. When switch production is completed , test results to the requirements of control.

Key Words: Sound, light and touch control ；delay control ；photoresistance；
