Abstract:
The project demonstrates a system that can be integrated as a single portable unit and allows controlling lights, fans, television sets etc. and to turn on or off any appliance that is plugged into a wall outlet. The overall system is controlled from a microphone which is connected with speech recognition chip. This chip sends the voice commands in binary sequence to microcontroller. The control unit takes decision and sends the commands to corresponding loads. A PIR sensor is used to switch off the loads when there is no person for a while time. If we forgot the commands, a button is used to retrieve the commands and displays on LCD.
Home Automation industry is growing rapidly; this is fuelled by the need to provide supporting systems for the elderly and the disabled, especially those who live alone. Coupled with this, the world population is confirmed to be getting older. Home automation systems must comply with the household standards and convenience of usage. The aim of this project is to provide those with special needs with a system that can respond to voice commands and control the on/off status of
electrical devices, such as lamps, fans, television etc, in the home. The system should be reasonably cheap, easy to configure, and easy to run. There have been several commercial and research projects on smart homes and voice recognition systems.
