1.1 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.
1.2 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
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).

1.5 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
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
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.
