X-10 is a power line carrier technology that allows device throughout the home to communicate with each other via the existing mains wiring in the house. X-10 uses 120 kHz bursts timed with the 240VAC power line zero-crossings to represent digital information. Transmitter burst the 120 kHz PWM signal using PIC16F877A into AC power line that have time of zero-crossing. Receiver was function as signal detector. Signal that has been detected from all the receiver circuit will be operated by the PIC16F877A. The X-10 technology is one of the easiest and most popular ways to automate home without re-wire our own house. Without it, we will spend a lot of money and time to do some maintenance in our house. Basic flows of X-10 power line system are input from computer was send to microcontroller using Visual Basic 6 software. Then, the input data send through mains power line by using coupling circuit in the modem transmitter. At the receiving end, data was passed through receiver modem and go to controller. Load was operated by controller depend on the input signal that has been send by the computer at the transmitting before.
