There is a circuit by which home appliances can be operated like lights and water pump from the user's office or any other remote place. It helps to turn off the appliance with cell phone. Cell phone works as the remote control for home appliances. The system also gives the user's voice acknowledgement of the appliance status. The technology used here is embedded system with mobile technology which is future of today's modern electronics. The circuit comprises microcontroller AT89C51, DTMF decoder MT8870, voice recording/playback device APR9600 and a few discrete components. Microcontroller is used here for centralized operation and digital processing.
