Research Electrical control system using smart phones will use the smartphone as a wireless remote control. Used to control the opening and closing electrical equipment. The objective is to enhance the comfort. You can turn on and turn off electrical equipment without having to walk to the switch panel. In experiments, the system will begin with the installation of electrical equipment and control applications in the smart phone support technology for Android Bluetooth. Select the command that you want from a smart phone to send a command to the Control Board, then follow the instructions. Test the functionality of the controls work fine without errors. Test distance send can send about 20 meters. Research indicates that Applications can actually be controlled with a smartphone and a control box. According to the design, Phase transmitter will send a signal to get far without an error of about 20 meters, according to the design.
