This paper details the overall design of a wireless home automation system (WHAS). This is fuelled by the need to provide supporting systems for the elderly and the disabled, especially those who live alone.
The automation centre’s on recognition of voice commands and uses low-power RF ZigBee wireless communication modules which are relatively cheap. The home automation system is intended to control all lights and electrical appliances in a home or office using voice commands.
The zigbee can receive the voice and send the voice data to the ARM9 controller and then the controller converts the voice into required format and then again send the data through the zigbee to the another zigbee and to the micro controller where the devices are attached to it. Based on the message it received it either turns ON/OFF the devices.
