Explanation:

• I want to make a device that can help to save electricity. I would like to make automatic electricity at home. It can be made by PIR Motion sensor, a human detection sensors, a battery, a cell and a device like a fan or a light.
• In this we can put a PIR sensors in the room and a human detection sersor at door, whenever the person get in the room the lights get on automatically due to sensors and whenever the person gets out it get off automatically. The need of PIR sensors is when there is two person in a room the light will not get off if person get out.
• The main aim of this device is to save electricity as it gets off when not in use, thus it saves electricity and also we can connect it with solar device for further saving electricity, it's cost efficient and can be used by everyone.
