INTRODUCTION Wouldn’t it be nice to have your home take care of your thing for you‚ automatically‚ without you having to lift a finger? You bet it would. This is the promise of Home Automation. There are many different systems‚ especially in larger homes‚ that can benefit from being integrated. Some of these systems include security alarm‚ HVAC‚ audio/video & lighting. Home automation integrates together‚ enabling them to function more efficiently‚ improve functionality‚ conserve resources & enhance

detector (sometimes called a crystal detector) is an antique electronic component consisting of a thin wire that lightly touches a crystal of semiconducting mineral (usually galena) to make a crude point-contact rectifier. Developed by early radio researchers Henry H. C. Dunwoody‚ G. W. Pickard and others‚ this device was used as the detector in early crystal radios‚ from about 1906 through the Second World War‚ and gave this type of radio receiver its name. Crystal radios were the most popular type

chapter 1 intaoduction “Driving to save lives‚ time‚ and money in spite of the conditions around you and the actions of others.”- This is the slogan for Defensive Driving. Vehicle accidents are most common if the driving is inadequate. These happen on most factors if the driver is drowsy or if he is alcoholic. Driver drowsiness is recognized as an important factor in the vehicle accidents. It was demonstrated that driving performance deteriorates with increased drowsiness with resulting crashes

chapter 1 introduction 1.1GENERAL With the increasing denial of time and space the RFID technology is gaining momentum day by day. RFID is a source of identification of individuals and unique products. The budding technology RFID proves to threaten even the cloning technique‚ through the chip insertion. New ways of improving the existing RFID technology are being found and implemented. This advancement of RFID technology is looked beyond the security purposes. 1.2 PRESENT SCENARIO

1.INTRODUCTION EMBEDDED SYSTEMS Embedded systems are designed to do some specific task‚ rather than be a general-purpose computer for multiple tasks. Some also have real time performance constraints that must be met‚ for reason such as safety and usability; others may have low or no performance requirements‚ allowing the system hardware to be simplified to reduce costs. An embedded system is not always a separate block - very often it is physically

IC 7805- The input voltage must always be higher than the output voltage by some minimum amount (typically 1.5 to 2 volts) . 7805 is a linear voltage regulator‚ so it is not very efficient and it has drop out voltage problem. As they are based on a linear regulator design‚ the input current required is always the same as the output current. As the input voltage must always be higher than the output voltage‚ this means that the total power (voltage multiplied by current) going into the 78xx will be
