基于AT89C52的声光节能控制器 Based on the help of AT89C52 energy saving controller 摘□要 生活中我们用的最为平常的灯则是楼道里的照明灯，住过居民楼的人都应该知道，楼道很窄，晚上行走很不方便，如果让楼道的照明灯一直亮着，则难免会浪费国家资源，因此设计一种既不浪费国家电力又很方便实用的照明灯系统是很有实用价值意义的一件事。 随着电子技术的发展，尤其是数字技术的发展，用数字电路技术实现灯的自动发亮、节能节电变得越来越重要，而且贴近我们的实际生活。声光控电路已成为人们日常生活中必不可少的必需品，它不需要开关，当有人经过时会自动的亮；广泛应用于走廊、楼道招待所等公共场所，给人们的生活、带来极大的方便。因此，得到了广泛的应用。声光控电路是声音和光控制电路工作的电子开关。该电路由电源电路、声控电路、光控电路和延时控制开关电路等组成，它不仅广泛适用于楼梯间、过道库房等场合，而且节能省电，使用方便。 【关键词】 Based on the help of AT89C52 energy saving controller Abstract Life the most common we use is in the corridor of the lamp lights, lived the dweller building would know that corridor is very narrow, the evening walk is not easy, if let corridor floodlight has been on, it will be hard to avoid waste state resources, so the design of a doesnt waste national power and very convenient and practical floodlight system is very practical value significance of one thing. With the development of electronic technology, especially the development of digital technology, a digital circuit technology to realize the light shine, energy saving electricity saving becomes more and more important, and close to the actual life. Sound electric circuit has become necessary in Peoples Daily life necessities, it does not need to switch, when someone after will be light; Widely used in the corridor, corridor hostel and other public places, to the life of people, bring great convenience. Therefore, a wide range of applications. Sound electric circuit is sound and light control circuit work electronic switching. The circuit by power supply circuit, sonic circuits, electric circuit and control circuit switch and other components of the delay, it not only widely applicable to the stairs, corridor warehouse and so on, and energy saving save electricity and easy to use. 【Key words】sound transducer 目 录 1.引 言 1 1.1声光控制概述 1 1.2 声光控制节能的意义 2 2. 声光控制开关 3 2.1声光控制开关原理 3 2.2声敏传感器模块 7 2.3光敏传感器模块 8 3.
