ABSTRACT

This project was made to present the electric energy arrangement method

which will be appropriate for energy use and energy using demand. To take the

most worth, this project will apply the existing technology to design the circuit

which is to turn on/off the electric appliances, for instance the light, fan and air-

conditioner by using the two conditions, the number of people and room

temperature, to control turning the electric appliances on and off.

This project was made in model to demonstrate the procedure controlling

the electric appliances which are in line with the conditions in accordance with

the use appropriation.

Due to the assumption, this project achieves that the process worksfollowing the above conditions. The sensor detects the human motion in kind of

coming in-out the room, as a result, the number of people and temperature will

be changed and indicated by the light.
