I. INTRODUCTION In modern era, the technology is constantly enhancing providing new demands for automation market and more complex issues for engineer and automation enthusiasts. The methods used for home automation usually consist of one or two control techniques which proposes a relatively simple model for home automation system (HAS). In our current work we propose a complex electrical / electronic controlled automation systemwhich gives us real time control over appliances and equipment. As the technology is progressing, home automation systems are currently in more demand as devices are integrated with each other and can work as an automated control network. The automated control network not only controls our environment but brings efficiency and comfort for various tricky jobs like security management, instrumentation management and many other control areas. These comforts can be implemented by voice recognition by which a user can control by means of his vocal voice or by providing pattern recognition by means of image processing for automated control by recoding an ideal scenario as a preset or controlling all such controls over TCP/IP or GSM network. Providing a sophisticated home / industrial control environment is nowadays a primary need of every control environment. We can say the proposed smart home auto mation system can be a perfect environment for an expert system, it can manage the home/controlling environment in a convenient way it could prove t o be quite efficient to perform goals like managing temperature of the environment while conserving energy, by using the preset temperature reading, present data or conserving energy by using motion sensor. The systemis designed to be of adaptive nature and can easily adapt the present environment by collecting the data fromthe intelligent sensor network desig ned to provide real time feedback. The system is designed to be of flexible and accommodative algorithm and can be incorporated with any existing system. The mentioned system can be called as a near perfect environment for an expert system, as it can manag e home in a convenient way, proving quite efficient in performing several of our daily tasks like conserving the electricity, or managing the home temperature environment or automatic control by various sensors . The mentioned systemcan also be programmed to be of custom settings or preferences which can be used for automatic actuation of temperature, time, light, motion etc. The system is mainly incorporated with four top technologies providing a very sophisticated control over appliances and devices. The technologies included in this project are Bluetooth, GSM, biometric scanning and voice recognition. The combination of these four methods not only adds complexity in the system for the engineer but also carries the user to a very comfort zone. The systemcan also be said as a merger or both wired and wireless medium, providing in-house and remote access to the home. The wireless communication medium, Bluetooth and GSM communication are being interfaced with android operating system which is based on Linux operating system designed mainly for touch screen mobile phone devices and tablet computers. It is an open source code and accommodating licensing enables the engineering enthusiast / programmers to develop more control
programs on it. Android devices are known as smart devices, and with time only will get smarter, with new features which are not available on any other platform. Android powers hundreds of millions of mobile phone devices in many countries around the globe. It is the biggest installed operating system base of any mobile platformand increasing rapidly every day. Millions of user power up their Android devices for the first time and start looking for applications, games, and other digital content availa ble on its platform. The user interface of Android is focused on direct operation using touch inputs that slackly match to real-world actions, like swiping, and tapping to control on-screen objects. The response to user touch input is planned to be instantaneous which provides a flowing touch interface. The wired medium, Voice recognition and biometric scanner are being interfaced with an embedded system which can work only when the user is physically present and authenticated. In this paper, the proposed automation method is of the home and industrial automation which is analyzed in small premises. II. SYSTEM DESCRIPTION The Project is multiple control method based home automation (HAS) design architecture, which propose both wired and wireless control for automation. The wireless control are separated and are controlled by an android mobiles GUI, it not only provide remote function for a larger coverage but also in-house security and authentication system.
