In the recent years, the Home Automation systems has seen a rapid changes due to introduction of various wireless technologies The explosion in the wireless technology has seen the emergence of many standards, especially in the industrial, scientific and medical (ISM) radio band.
ZigBee is an IEEE 802.15.4 standard for data communications with business and consumer devices. Zigbee is targeted at applications that requires low data rate, long battery life, and secure networking. Zigbee has a defined rate of 250 kbits/s, best suited for periodic or intermittent data or a single signal transmission from a sensor or input device.
The wireless home Automation systems is supposed to be implemented in existing home environments, without any changes in the infrastructure. The automation centers on recognition of voice commands and uses low-power ZigBee wireless communication modules along with microcontroller.
Voice Recognition Wireless Home Automation System
This system is most suitable for the elderly and the disabled persons especially those who live alone and since recognize voice so it is secure. The home automation system is intended to control all lights and electrical appliances in a home or office using voice commands. So in this paperwork our aim is to designed a voice recognition wireless ZigBee based home automation system.
