CHAPTER 1 INTRODUCTION This project is mainly used to save power automatically instead of doing manual by using IR sensors The main consideration in the present field technologies are Automation‚ Power consumption and cost effectiveness. Automation is intended to reduce man power with the help of intelligent systems. Power saving is the main consideration forever as the source of the power(Thermal‚ Hydro etc.‚)are getting diminished due to various reasons. Wireless communication

stage (40dB) and 10 times (20dB) at the next stage. As for the dB (decibel)‚ refer to "Logarithm Table". Generally‚ the positive and the negative power supply are used for the operational amplifier. The circuit this time works with the single power supply of +9 V. Therefore‚ for the positive input of the operational amplifiers‚ the half of the power supply voltage is appied as the bias voltage. Then the alternating current signal can be amplified on 4.5V central voltage. When using the operational

The home appliances control system with an affordable cost was thought to be built that should be mobile providing remote access to the appliances and allowing home security. Though devices connected as home and office appliances consume electrical power. These devices should be controlled as well as turn on/off if required. Most of the times it was done manually. Now it is a necessity to control devices more effectively and efficiently at

INTRODUCTION For years‚ infrared LED has been merely a system for piping light around corners and into the inaccessible places to allow the hidden to be lighted. But now‚ infrared LED has evolved into a system of significantly greater importance and use. Throughout the world‚ it is now being used to transmit voice‚ television and data signals as light waves. Its advantages as compared with conventional coaxial cable or twisted wire pairs are manifold. As a result‚ millions of dollars are being spent

line of nomenclature blurs even more. Physically‚ embedded systems ranges from portable devices such as digital watches and MP3 players‚ to large stationary installations like traffic lights‚ factory controllers‚ or the systems controlling nuclear power plants. In terms of complexity embedded systems can range from very simple with a single microcontroller chip‚ to very complex with multiple units‚ peripherals and networks mounted inside a large chassis or enclosure.

Chapter 1 Introduction 1.1 Introduction: Wireless communication has announced its arrival on big stage and the world is going mobile. We want to control everything and without moving an inch. This remote control of appliances is possible through Embedded Systems. The use of “Embedded System in Communication” has given rise to many interesting applications that ensures comfort and safety to human life. The project mainly focuses on transmission of textual data through air interface by the use
