CHAPTER ONE
INTRODUCTION

OBJECTIVE OF PROJECT
The need for a remote control alert system that can
control domestic appliances and various lighting points and sockets has often
been a concern for users. At times users find it inconvenient and time
consuming to go around turning their appliances on or off each time there is
power outage or each time they are leaving the house for work. It has also
often led to damage of appliances due to the fact that an appliance was not
turned off before leaving the house.
The Objective of putting up this
project, therefore, is to design an equipment that can facilitate a convenient and
easy way of controlling our domestic appliances, lighting points and sockets
especially in powering them, without always going to appliances physically by
ourselves.
This
objective will be accomplished using various components which include a Microcontroller
(AT89C51) which acts as the backbone of the project together with other
components.

JUSTIFICATION OF PROJECT
The ease of putting our appliances, lighting points
and sockets on or off has made it necessary to develop this system in order to control
our appliances, lighting points and sockets from a central point using a remote
control. The issues of always forgetting our appliances ON when leaving the
house has often caused fire outbreak and explosion in homes and this is another
reason that led to designing and construction of this project.
1.3 SCOPE OF DIAGRAMS IN PROJECT
In this project report, the diagrams will range from simple block
diagrams to complex circuit diagrams which will comprise mostly of common
electrical and electronics symbols. Some of the diagrams that will feature in
this report will be used as the main block on which certain parameters will be
explained upon. Relevant electronic components will also be shown and
described.
This project report will also contain an outline of the circuit diagram
as it is seen physically. The package design diagram will be included showing
the width, height in millimeter (mm).

PROJECT REPORT ORGANIZATION
Chapter 1 serves as the introductory chapter where I
try to relay the concept and acceptable reasons why the project should be
implemented for the intending user of the work. Thus, showing the block diagram
of the design and a scope of diagram for the entire project design.
Chapter 2 deals with the literature review where it
will be discussing the origin of this project design. In the origin of the
project, we will be looking at what brings about the three phase selector in
our day to day activity and how the idea of designing this project comes about.
A description of the Project is also given where the
2 sections of the project are discussed and the various components contained in
the sections also mentioned.
The
use and importance of this project design will also be mentioned here. It will
be looking at the best place where this project design can be use and where it
cannot. This chapter will also make room
for adding additional information that will help in the actualization of this
project design.
Chapter
3 treats the methodology of this project design. It comprises of the
information gathering; the source of the materials used in designing and
writing the project report, data analysis; the components and devices used in
the course of designing this project will be analysis to know their basic means
of operation and how they will help in putting up this design, system design
approach; the possible way to tackled the project design from scratch,
bottom-up; it will treat how the practical detail was gotten before considering
about the general principle of the system design, choice of design system; it
focuses on why the project design was done using a microcontroller rather than
using only digital logic, and also the data flow arrangement and system flow
chart.
In
chapter 4, the detail design work will be presented. It will include the
schematic of the design of the various sections of the design and the source
code (in C language) used in programming the microcontroller.
Chapter 5 will be discussing the system testing,
Expected results, and Performance evaluation.
Summary and conclusion of the design will be
presented in Chapter 6. It will be looking at the problems encountered in
designing the project and possible solutions to them. From the problems and
solutions of this work, the suggestion for further improvement will be stated.
