光控智能开关的设计及实现 随着社会的进步，人们越来越倾向节能、环保、智能。传统的照明灯，在一些场合，比如楼道、卫生间、小巷等，往往造成资源的浪费。 用声光控开关代替住房楼道上的开关，天黑以后，当有人走过楼梯通道，发出脚步声或其它声音时，楼道灯会自动点亮，提供照明，当人们进入家门或走出公寓，楼道灯会自动熄灭。在白天，即使有声音，楼道灯也不会亮，可以达到节能的目的。声光控开关不仅适用于住宅区的楼道，而且也适用于工厂、办公楼、教学楼等公共场所，它具有体积小、外形美观、制作容易、工作可靠等优点，适合于各种楼房走廊的照明设备。 降低能耗、节约能源、注重环保是当今世界的主潮流，高能耗且会加剧温室效应的白炽灯越来越不受欢迎。 声光控电路是声音和光控制电路工作的电子开关。它将声音（如脚步）和光转化为电信号，经放大、整形，输出一个开关信号去控制各种电器的工作，在自动控制工业电器和家用电器方面有着广泛的用途。由于，本电路广泛应用于人们的日常生活中，所以，有重要的现实作用。　　 光敏电阻驻极体传声器声光控节能，电阻，电容 Intelligent light control switch design and implementation ABSTRACT Along with the progress of the society, people are more and more tend to energy saving, environmental protection, intelligence. The traditional lights, in some cases, such as corridor, toilet, lane, etc, often cause waste of resources. Instead of using sound and light control switch on the switch housing corridor after dark, when someone walked staircases, issue footsteps or other sounds, corridor light will automatically light up, to provide lighting when people enter the house or out of the apartment, corridor light automatically turn off. During the day, even if there is sound, the corridor lights are not bright, you can save energy. Sound and light control switch applies not only to residential corridor, but also suitable for factories, office buildings, school buildings and other public places, it has a small, beautiful appearance, easy to manufacture, reliable work, etc., suitable for a variety of buildings corridor lighting equipment. Reduce energy consumption, save energy and environmentally conscious is the main trend in todays world, high energy consumption and exacerbate the greenhouse effect incandescent increasingly unpopular. Sound and light control circuit is a sound and light control circuit electronic switch. It sounds (such as footsteps) and light into electrical signals, amplified, shaping, outputs a switching signal to control a variety of electrical work in the automatic control of industrial an
