 IVRS based home automation with immediate voice feedback

This project is used to automate the house. This project has a provision for Switching of house hold devices like Fan, Tube lights, Televisions etc through telephone from anywhere in the world, as well as from your very own house using blue tooth technology. To make this project work with two different technologies, we have used two different microcontrollers with the same hardware.

TELEPHONE NETWORK

The telephone network is achieved with the use of an Embedded Microcontroller and a Telephone Circuitry. To accomplish this, a call is made from a remote telephone or Cell phone. Once the Call is made our telephone circuitry identifies it and establishes the call. Now the remote user can press the particular no for Switching on or switching off the devices. And then by entering the # key he can disconnect the call.

The one main advantage of this project is we can get the feedback through Voice. I.e., after switching on a device we can hear a message in the cell phone stating that the “Air Conditioner Switched ON”.
