From the block diagram. The system starts from the creation and design Applications onto a mobile phone operating system, Android, to control the operation of electrical equipment by secretly sending the application data into a database and data retrieval will be microcontroller through the Wi-Fi Module to control the operation of the relay to turn on-off. Electrical equipment. There is also a lotruat module installed motion sensor (PIR) to open-close the electrical equipment and sensors to check meter to check the status of the electrical equipment and then send data to the microcontroller, and store into a database, then the application will retrieve the status of the power device is displayed on the handset screen.
