ABSTRACT

This study is about creating a web based light control system which further will be controlled by

android phone. The purpose of creating this system is to enhance proper use of light in houses,

homes, offices, industries and factories. One will be able to check whether the lights are on or off

using the phone and decide to switch off or on regardless of where one is. This will help in

cutting down of the unnecessary electricity cost and in so doing it will factor in cutting down the

cost of living. The button on the android phone will be able to control a web server which will be

able to communicate with the Socket directly using the Heyu software. The proposed system

aims to make all these operations more effective and the tasks to be more efficient.

Chapter one gives a brief description of the project including the problem statement, the

background study, scope, justification and limitation. Chapter two gives the literature review of

the system and chapter three covers the methodology used, tools for collecting, analyzing and

implementing the data.

CHAPTER ONE

1.0 INTRODUCTION

1.1 BACKGROUND OF THE STUDY

In our country today most persons are connected in the grid. Especially with the project of rural

electrification not only are those living in towns can access electricity but also those in rural.

Electricity come with a cost and thus getting a way to cut down unnecessary costs that arise due

to improper use becomes a key priority.

Due to the increase in the cost of living unnecessary cost in the electricity bills only means

making life even more difficult. These costs arises when one forgets to switch off the lights when

in hurry especially when one is late at his working place, forgetting to put off the socket after

cooking using the electric coils and so on.

The proposed automated light control system will enable one to be able to check the status of the

light in his or her place and take appropriate action. In so doing there will be saving of energy

which will directly lead to reduction in the bill hence cost of living will eventually drop.

The full adoption of the system will also see the country global domestic product(GDP) grow

due to the injection of taxes in the system and in so doing these will also improve the economy

of the country.

The system will not only improve the life of citizens in the country by cutting down on the cost

of living but also improve the country’s economy at large.

1.2 PROBLEM STATEMENT

Electricity is so crucial in our day to day operation. We need light at night, we need power to run

turbines and drive industries and factories. We need light for cooking, learning and in

transportation just to mention few.

People usually use the light and sometimes forget to switch the bulb off when they are not in use.

These practices also happen at offices, homes, learning institutions and factories. These increases

the unit of power consumed and leads to higher electricity charges. This challenge can become a

history once the system is adopted. When one will realize the lights were not off he/she will be

able to switch it off from wherever they will be at any time as long as the system is operational.

The automated proposed light control system aims at solving these challenges by directly

monitoring the lights condition and communicating the status which one can be able to check

using the android phone and decide on the appropriate solution. There will manage how one uses

the light and in so doing directly controls the unnecessary cost on the electricity bills.

1.3 OBJECTIVES OF THE STUDY

This study will be guided by these specific objectives:

To develop a control system that would monitor the condition and status of light in the

buildings.

To develop an automated light control system that would allow for easy control of light

using android phone.

To implement the system.

To validate the system

To apply the chosen methodology in the development of the system

1.4 JUSTIFICATION

The increase in the cost of living facing most persons today calls for availability of a way to help in cutting down the cost. The cost becomes even more due to unnecessary electricity charges added to the bills. Since the extra charges can be controlled and eradicated, this calls for a control automated system to do so.

Due to increase in technology the automated system will be available in android phones which almost every one can afford. By pressing a button one will be able to reduce the cost of using lights and directly cutting down his/her cost of living.

The electricity provider bodies like Kenya Power and Lighting Company (KPLC) will also benefit from the proposed system since the system will see the country economy shoots and there profit will also increase because they will be taking less from the generating stations.

1.5 SCOPE AND LIMITATION

1.5.1 Scope

The automated light control system manages the monitoring and controlling of lights in the

buildings. The system which will be configured to an android mobile app which be able to

monitor the web server activities and regulate them as required. The ruby on rails server will

control the Heyu software activity of monitoring the switch lights and the whole process will be

real time.

1.5.2 Limitations

However the light control system has the following limitations;1. Only person with android phone will easily access the service.2. The Control operation needs internet to operate.

CHAPTER TWO

2.0 LITERATURE REVIEW

The existence of technology proves to be a reliable source of creation and novelty especially

when it comes to development of the IT products and automated systems. Cawson et al (1995) is

has an opinion that lands on technology is the facilitator of the innovation process aimed at

shaping things for customers. The improvement process narrows down to the way new IT

products suppliers incorporate the knowledge of clients in designing the appropriate systems.

Development of the light control automation systems can be facilitated by the wide use of sensor

(android) network that essentially reduces the number of sensors used in automated system (Reza

Mohamaddoust, 2011). Mohamaddoust and his colleagues discovered the importance of

directing greater efforts towards optimizing electrical energy utilization through the relevant use

of the wireless sensor networks which directly contribute to the energy conservation applications

such as light control.

The efficiency of the sensors and their wide use can be achieved by an extended use of the microcontrollers. Mustafa et al (2010) developed an embedded system for energy saving of street lights. The central use of the microcontrollers plays a focal role of automating the functionality of the street light control system. Incorporation of the microcontrollers in designing the new streetlight system aims at cutting down on the huge consumption of electricity.

It is also important to recognize the value of the wireless lighting control as well as the need to save energy as it will be seen in some quoted cases revolving around the United States environs (Daintree Networks Inc., 2010). The lighting control system functionality include the on/off and dimming controls, occupancy sensing, photo sensing, scheduling the turns on and off, centralizing the control system interface, establishing a communication system between the lighting equipment and the control system as well as settling on an outstanding method of displaying, measuring and responding to lighting energy usage. An argument on energy monitoring settles on the idea of a better data equals a better saving and this begins with advanced water lighting control systems.

(Abdelrasoul Jabar Alzubaidi, Arwa Abdel Mohsen Ahmed Hassan, 2014), proposed an automated traffic light

control system because the current have some limitations due to using a pre-defined hardware, which is programmed according to fixed time that never change. Hence, there is no flexibility of modification on real time basis. These calls for modern automated flexible.

2.1 CASE STUDIES

2.1.1 CASE STUDY 1: Automatic Street Light Control System

Automatic Street Light Control System is not only a simple but also the powerful tool to control light during the night and day. Relay uses as an automatic switch in this system. It is functional 100%. As soon as the sunlight sets this system automatically switches ON lights. Light Dependant Resistor (LDR) is a type of sensor which performs this work and senses the light as our eyes does. As soon as the sunlight comes, it automatically switches OFF lights. Such type of system is very useful for reducing energy consumption.

2.1.2 CASE STUDY 2: Microcontroller Based Automatic Water Level Control System

The subsequent use of the microcontrollers is further seen in the development of the microcontroller based automatic water level control system, a project developed by Ejiofor and Oladipo (2013), based on the principle of inter-operability. In their project, the two considered the joint operation of the sensors, microcontroller, comparator circuit, display unit and the pump. Copper conductors are therefore used as water level sensors given the fact that water poses the electrical conductivity property. When the water touches the copper sensor, voltage is transferred to the comparator circuit for further processing. The comparator may either give a LOW or a HIGH depending on the level of water in the tank. This is further fed in the microcontroller, which further uses the information in controlling the water pump. The LCD screen serves as an output unit while the functionality of the entire system is controlled by the programmed assembly language in the Atmel 89C52 microcontroller

CHAPTER THREE

3.0 METHODOLOGY

Methodology is the systematic, theoretical analysis of the methods applied to a field of study. There are several methodologies that can be used to design and develop a system for example scram, prototyping and Structured Systems Analysis and Design Methodology(SSADM).

3.1 Prototyping methodologyIn prototyping methodology, analysis, design and implementation phases are performed concurrently, and all the three phases are repeatedly in a cycle until the system is completed. In this methodology, the basics of analysis and design are performed and work immediately starts on a system prototype. The prototype is a quick and dirty program that provides minimal amount of features. The first prototype is the first that the user will use, and provide comments, which are often used to reanalyze, redesign and reemployment. A second prototype provides a few more features. Then the cycle continues till the system is accepted. The major disadvantages of prototyping are that the fast paced system releases challenge to careful methodological analysis, which makes the initial designs very poor

3.2 Scrum methodologiesThis method is based on iterative and incremental software development where requirements and solutions evolve through collaboration between collaboration between self organized cross functional teams. It allows project participants to adjust themselves and their activities in response to situations that arise during the project development process, requirements are implemented into system functionalities as soon as they are identified, the necessary tests carried out and this is repeated until the whole system is developed.3.3 SSADM methodologyThe development of the proposed system will be in Structured Systems Analysis and Development Methodology (SSADM). Design is not affected by existing methods.

It uses well defined techniques and documentation. It takes into concern user involvement. Every stage is terminated by a quality review which is staffed by people with mixed

experience, some of whom are not directly connected with the project.

Design

Figure 1: design

3.2 Data Collection tools

The following techniques will be used to identify and gather data and requirements needed for the development of the proposed system.

3.2.1 Interviews

The researcher will conduct a one on one interview with various respondents. It will be a

reliable method in that first-hand information will be collected. The plant owner, managers and

employees will be interviewed to determine the specific requirements needed by each party.

3.2.2 Observation

In this method, the researcher will study the interested areas and come up with the necessary

conclusions. A visit to the plant to observe how they operate will help to note what the

respondent fails to pass forward. This will involve close interaction with the plant’s employees

as they process the birds to see how the activities are carried out, the sequence in which they are

carried out and what their deliverables are.

3.2.3 Document Review

The existing system’s records will be studied so as to know; what to be used, what not to be

used, or what will be missing; what will work well, what will not work; how the system is used,

how it was supposed to be used, and how the study would like to use it. The records will include

data about how the current system operates in processing of the birds through to their delivery to

the customers as well as how the employees, customers and suppliers are managed and all the

calculations involved.

3.3 Data Analysis Methods

The following tools will the used to analyze the data and the process.

a) Data flow diagrams (DFDs)

Data flow diagrams illustrate how data is processed by a system in terms of inputs and

outputs. They describe how the system transforms the data and how the data is processed

as well as how the data is stored. They also depict how the data flows through the

processes. The DFDs will be used to show how information flows through the different

levels of poultry processing.

b) Flowcharts

A flow chart is a means to visually present the flow of data through an information

processing system, the operations performed within the system and the sequence in which

they are performed. It is a diagrammatic representation that illustrates a solution model

to a given problem .This will be used to analyze the processes that are take place during

the processing of a chicken.

c) Use case

A use case is a collection of possible scenarios related to a particular environment. Use

cases will be used to make up of a set of possible sequences of interactions between the

system and the users in the poultry plant.
