Abstract:

There is a circuit by which home appliances can be operated like lights and water pump from your office or any other remote place. It helps to turn off the appliance with cellphone. Cell phone works as the remote control for home appliances. The system also gives you voice acknowledgement of the appliance status. The technology used here is embedded system with mobile technology [1] 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. [2] The APR9600 device offers true single-chip voice recording, non-volatile storage, and playback capability for 40 to 60 seconds. Port pins are configured to receive the decoded DTMF signal from DTMF receiver MT8870. The DTMF decoder is used for decoding the mobile signal. It gets DTMF tone from the mobile headset’s speaker pins and decodes it into 4-bit digital signal. This device is very useful to operate any electronic equipment from miles away as in rural areas , agriculture, home, factories etc.[3] Future scope of this technology is we can use video facility in our circuit. It is useful for security purpose.
