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

DTMF BASED HOME APPLIANCE CONTROL SUBMITTED BY ABSTRACT Traditionally electrical appliances in a home are controlled via switches that regulate the electricity to these devices. As the world gets more and more technologically advanced‚ we find new technology coming in deeper and deeper into our personal lives even at home. Home automation is becoming more and more popular around the world and is becoming a common practice. The process of home automation works by making everything in the house

CHAPTER TWO 2.0. LITERATURE REVIEW In a commercial transaction system‚ a system user uses a card device to interact with sales or transaction terminals to conduct cashless transactions. Each terminal processes data including a balance stored on the card device and updates the stored data at the end of the transaction. The system is specially designed for purchases of items or transactions of relatively small monetary value‚ where purchases are generated unattended by salespersons. In this manner

Chapter Three System Design and Methodology 3.1 Design Outline of the System The process of circuit design begins with the specification‚ which states the functionality that the finished design must provide‚ but does not indicate how it is to be achieved. The initial specification for this project is a dc voltmeter with an input voltage range of 0 to 300 volts. Although there are many parameters that a design specification should contain‚ such as size‚ weight‚ moisture resistance‚ temperature

ABSTRACT Flood is one of the disastrous phenomena that caused a lot of deaths to some other uninformed area in the province. The researchers from Negros Occidental High School proposed a study with the objective to construct and develop a flood detection device‚ present a practical device‚ and introduce the device to a certain residents in the province that needs to be aware of flood. After the device was constructed‚ the researchers tested the device in a cup of water. During the testing of device

CHAPTER 1 INTRODUCTION 1.1 GENERAL Nowadays‚ there is a demand of power supply. As an electrical engineer‚ it is necessary to design system with low cost‚ reduced losses and higher efficiency. This paper proposes nine-switch converter with single controller‚ rather than using 12 switches for operation of drives separately. In electrical vehicle drives mostly AC motors are used. It is because of its well known advantages like simplicity‚ reliability‚ lack of mechanical commutator

CHAPTER 1 INTRODUCTION 1.1 INTRODUCTION: 1.1.1 EMBEDDED SYSTEM: An embedded system is a special-purpose system in which the computer is completely encapsulated by or dedicated to the device or system it controls. Unlike a general-purpose computer‚ such as a personal computer‚ an embedded system performs one or a few predefined tasks‚ usually with very specific requirements. Since the system is dedicated to specific tasks‚ design engineers can optimize it‚ reducing

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
