This document describes a voice recognition based wireless home automation system using an ARM-7 microcontroller. The system allows users to control lights, fans, air conditioners, security cameras and other devices through voice commands to the portable unit. The system is designed to be easy to install, configure, run and maintain for elderly and disabled users. It uses an ARM-7 microcontroller for data communication and voice recognition between connected devices in the home. The hardware components include an ARM development board, relay circuit, USB programmer and connecting wires. The system is programmed using embedded C on a KEIL IDE and can be applied in homes, industries and colleges to control appliances and machines through voice.

2. INTRODUCTION
 The Wireless Home Automation System is an integrated system to
facilitate elderly and disabled people with an easy-to-use home
automation system that can be fully operated based on speech
commands.
 The system is portable and constructed in a way that is easy to install,
configure, run, and maintain.
 The project demonstrates a system that can be integrated as a single
portable unit and allows one to wirelessly control lights, fans, air
conditioners, television sets, security cameras, electronic doors, computer
systems, audio/visual equipment’s etc.

3. ABSTRACT
 Abstract : 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. ARM-7 is an advance processor which are used for a data
communications with business and consumer devices. ARM-7 is targeted at
applications that requires low data rate, long battery life, and secure
networking The wireless home Automation systems is supposed to be
implemented in existing home environments, without any changes in the
infrastructure.. 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 ARM-7 based
home automation system.

4. ARM-7(MICROCONTROLLER)
 What is ARM?
Advanced RISC Machine
 RISC Microcontroller
ARM7、ARM9、ARM9E-S、StrongARM, ARM10…..
The original ARM7 was based on the earlier ARM6
design and used the same ARMv3 instruction set.
The ARM710 variant was used in a CPU module for
the Acorn Risc PC, and the first ARM based System
on a Chip designs ARM7100 and ARM7500 used this core
