摘要
介绍一种由单片机、热释电传感器、光强检测电路及延时选择电路模块组成的智能节电控制系统,该电路以STC单片机为控制核心,加以相关的硬件电子电路,利用热释电红外传感器检测有无人在。利用光敏电阻监测光的强度,确定是否需要光照。光照强度不足时,且监测有人,则启动光照电源。光强不足但无人时不启动光照电源。光强足够时,自动切断电源。本设计能够起到节能与断电保护的作用。延时时间可以设定。光强等参数可修改。
Introduce a single-chip, pyroelectric sensor, light intensity detection circuit and a delay circuit module is composed of intelligent energy saving control system, the circuit with STC MCU as the control core, supplemented by the electronic circuit, the use of human infrared sensors detect anyone in. Use the photosensitive resistance to monitor the intensity of light, to determine the need for light. Light intensity is low, and the monitoring of people, starting the light power. Light intensity is insufficient but nobody does not start when the light power. Light intensity is sufficient, and automatically cut off the power supply. This design can play a role in energy saving and protection, Delay time can be set. Light intensity and other parameters can be modified.
