Electric circiut for lighting
Hello sir
I`m doing a project on energy conservation in lighting. Sir I`m planning to prepare a model for this. I need the circuit for the same. Circiut should be to automatically sense a person entering the room and switch on the lights and fans in the room. Similarly as he moves out. Power should be off. Can you please suggest a method for this. Or else at least guide me from where I can get this on net? Waiting for your reply Vrinda |

What you need is called an Occupancy Sensor. They are available from many manufacturers, suchas Hubbell, Watt Stopper , Leviton, Sensor Switch, Watt Watcher, P&S, almost any manufacturer of wiring devices make some sort of sensor.
If you have lights and a fan that are separate circuits, look for either a two circuit sensor, or a sensor that can control a two circuit power relay. |
