摘要：The daily increasing demand of electricity in modern life leads to abundant usage of electric resources.The household electric loads like electric fans, lights which are commonly used for almost 24 hours in a day oftenconsume extra amount of power as people forget to switch off them even they go out of the room. An automaticswitching-off of electrical loads has been proposed in this paper by counting the number of visitors in the room in orderto avoid excess consumption of electrical power. The electrical loads will be switched off by use of a digital counterwhich will continuously monitor the incoming and outgoing of visitors and disconnects the circuit when visitor countbecomes zero.
