Abstract
The home automation system is indeed a system that offers a mobile application to monitor it through the smartphone or
tablet. It can control home appliances like light, fans, air conditions, and smart security locks, etc. Bluetooth or Wi-Fi is used for
remote control of things. Smart home is essentially how it looks: automating with such an easy touch of a button or a voice command
the ability to manage things across the home. Several operations were both simple and extremely low-cost, such as setting up a light
to turn on and off at the time of your moment. Others need much more money and resources, including advanced spy cameras. Some
people thought that technology is taking a really huge part of our lives. It does! we’re living in a modern generation where smart and
intelligent systems are necessary to be there wherever we are to make our lives easier and much better, for example, we can do many
things faster, better, and more accurate.
Keywords: Smart Home, Internet of Things, Smart Cities, Arduino, Mobile Apps.

1. Introduction
Through the years when smart systems were the only topic that all people talking about, a group of some persons
had an idea to improve the living style and taking modern technology into consideration [1]. They found out that it would
be great if houses will have something similar to the way of human-like. For example, we might forget to turn the lights
off [2], so, we will pay money for that and we will regret it at the end of the month, so they had somehow an idea of
having a Home Automation Systems [3]. Home Automation Systems are applications that have the accessibility to the
whole house’s controls, such as, lights, TV, AC, garage, doors, and so on [4]. Home automation management systems
have always future hints. Lights will turn on when entering the room, Fans will be activated when the temperature is too
low, Allow the family members to enter the house throw security looks that can detect all of the family members [5].
Mostly, people will think this is unreachable, they will say it’s impossible but actually, it is true! The way that people
think is different from the way that we think as developers, they think it needs a lot of devices to control the entire house
fields, but, it doesn’t. All we need is one smart device to install the application that was programmed for a specific house
and then you can run this app as you want. Home automation systems built to be structured as the user required, it is
reachable [6].
Figure 1. Home Automation System Block Diagram
Figure 1 shows the structure of the Home automation system. Even though the system has the security part which is more
I like, it can detect the family members using a scanned face by saving them in the database and recall that part while
scanning, so it will immediately open the door when any member of the family is there [22,23]. During the calculation of
the percentage and of having a large amount of wasted electricity power in the last few years, and some other information
that the current systems have. Our aim is to have the ability to let everyone live on his own lifestyle, erasing the fear of
thieves and the shock after looking at the energy bill. No matter how hard we will work, no matter how much they want
us to risk, our point is walking away after recognizing the perfect smile of those users we have. We would define the
problem as follow: -
1. The common property of success and the ability to make the house as less energy cost as possible such
as having the safety power mood that will detect if there is no one inside a room for a couple of minutes it will immediately
shut the power off.
2. The tragedies happened to houses by thieves at late nights especially when the owners are not there
because their house doesn’t provide any security systems.
The blockchain technology is the novel approach to provide security of the data gathered from Bluetooth or wi-
fi [7], [8]. Now instead of turning all of these controls off by going to each button and switch them off, you can just use
your smart device and switch whatever you want off, indeed, it will reduce the time you take to make sure about all of
your house’s area and check all of the controls [24,25,26]. Our systems will also have less cost compared with any normal
electricity powers in case of power safety. No matter how big is your house, the system is capable of more than you will
ever imagine.
A questionnaire is a fast and effective method used to acquire information from a targeted group of people. By
coming up with a few questions designed to get suggestions and the opinions of the application users, we were able to
remove unnecessary functions and provide more suitable ones to implement in the application. 1) Have you ever heard
about Home Automation System? - they say it’s a technology that could be really helpful in the future. 2) Have you ever
used the Home Automation System? - we have the answers as expected, it’s mostly never used it before and this will lead
us to our goal which is letting everyone using the system easily and comfortably. 3) What would you prefer? - using the
system as a smart device application easier for most of the users because they can open the system faster and use it. 4) Do
you think it's a good idea? - yes, it’s a good idea because the said they are having a problem with the electricity cost
during the month. 5) Do you think it's useful? - yes, also because the users always facing the same problem for the huge
cost of electric power. 6) Do you think it will be easy to use? - yes, we are living in a modern century that everyone can
use smart devices so easily and they are familiar with this kind of technology.
The rest of the paper is organized as follows: Section II represents the literature review, section III represents
the components of the system, section IV shows the methodologies for software development, section V represents the
results and discussion and section VI shows the conclusion.
2. Literature Review
The Internet of Things(IoT) during the last few years was used so widely in the smart house systems [9], [10].
By controlling almost all appliances and security. The system consists of Arduino Uno Board, PIR sensor, temperature
sensor, gas sensor, power select, and web applications. GSM is used to communicate the microcontroller and the web
page and facilitates energy management. It also monitors the type of device encountered at home and activates the
operations. The sensor parameters will be stored in the cloud [27,28]. The system also can be used in mobile health care,
traffic management, and so others. In the 21st century, there was a man that had an idea which allowed him to access all
the devices. Now we can even access the internet with only one click. Home automation is a mobile application for the
safety and proper use of a human. In the last 10 or more years ago, we used to switch the home appliances manually.
Based on the difficult access. At the beginning of this new automation, it was not considered an effective method yet. As
technology has improved this system to control by Bluetooth modules. The problem with using Bluetooth is that it has a
limit of the wireless range, also a chance of interference with other devices using Bluetooth [29]. In advance, they made
this kind of automation to be used using Android by android mobile phones [11]. Lately, they figured out a system that
can control and monitor the home appliances using any device which has an internet connection.
In the last years, home automation has achieved a really great job and increased the comfy of a lifestyle.
Smartphones are used to control all of their home appliances. You can communicate with all the home’s controls using a
smart device including new techniques. We never forget how the home automation has extremely grown, these systems
have been created to improve the comfortability of a lifestyle especially for those who are elderly and disabled these
systems are designed by using a single controller that owns the ability control interconnected appliances such as lights,
TVs, and so on [30]. The most interesting thing is that you can control all of these appliances easily by using smartphones.
Home automation systems could be controlled throw some methodologies such as Bluetooth and Wi-Fi. Bluetooth is a
technique that is secured and low cost as well [31,32,33]. The hardware will be using an Arduino BT board and cell phone
is wirelessly using Bluetooth. The smartphone uses the application that allows the user to control these appliances. The
system also uses passwords to make sure it’s not going to be used by some others.

Voice recognition also implemented by a researcher. Android OS has a built-in voice recognizing feature ability
to control the home appliances from user voice commands [12]. The application converts the voice into a text after that it
sends that message to the Bluetooth module that is connected to the Arduino. The great thing of this voice application
transmit is that the user only needs to pronounce the application name throw the microphone and say the commands that
he wanted to do such as turn the light ON or OFF. By using this kind of home control, the user doesn’t have to do
anything except saying the words that the application will recognize to achieve these commands.
In this research, they've explained how the home automation system works. this system works in smart devices
using android application and gives the user some services to make this technology easy for controlling the house. These
services are connected and used by connecting the smart devices via Bluetooth technology but it can handle only 24
devises at most at the same time with more than 100m range of Bluetooth signals. but the problem in this research is that
the signal has a limited range to be controlled and it will not work with a big distance, also, it’s not supported by Wi-Fi
[34,35].
Figure 2. Home Automation System Structural Diagram
3. Smart Home Automation System Components
The following are the main components of the Smart Home Automation System.
❖ User interface
❖ Smart device
❖ Arduino
❖ Android application-based Wi-Fi
The home automation systems will provide the need and the user requirements to handle all of these problems
and tragedies that could happen in life [13]. Sometimes we can do something to handle these problems. But, sometimes
we’re so far away from home. Therefore, the best way to think about while you have this situation is by using these
modern systems, and it will be as follow: -
1. The system will reduce power consumption.
2. The system will also reduce manual power.
3. The system will work efficiently and effectively.
4. The system will work in real-life time.
5. The system is a real challenge for people.
6. The system has also powerful security.
7. The system will also include scanning cameras to support both cases which are recognizing the family
members and recording any sense of the presence of other people who are rounding the house
In order to fill the gap of wasting the power of electricity in the houses, we have the idea of saving this cost of
electricity which has been a problem in the last few years. Also, the security needed, especially when the owners are far
away from home in case of traveling or other reasons. Two main objectives will be covered along with this project:
1. Building an application to control the houses’ appliances.
2. Based on Wi-Fi connecting the house with the application.
The Functional Requirements are summarized as follows.
1. Ability to process data according to user choice.
2. Ability to apply the user commands immediately.
3. Ability to switch on and off the power.
4. Ability to recognize family members.
5. Ability to access Arduino using a smartphone.
The nonfunctional requirement is as follows.
1. Accuracy.
2. High security.
4. Methodologies
In this research, we use waterfall model, "It defines some basic tasks, which are carried out in sequence
requirements definition, architecture design, detailed design, implementation, component verification, integration
verification, and requirements validation. Each task results in documents or other artifacts that are used as specifications
for the next task, e.g. the detailed design specification forms the basis for implementation task. In the "ideal" form, one
task should be completed before the next starts. There are however variants with overlapping tasks, and these are probably
used more in reality. Implementation starts when some of the detailed design is ready, component tests when components
are implemented. The following tools are used in the development of the system.
circuito.io: is a software that uses to design the block diagrams and electronic circuits.
Tinkercad: It is a software that uses to design the hardware.
draw.io: It is used to design UML diagrams.
Erdplus: is used to design an entity-relationship diagram.
Justinmind: is a software tool uses to make and build the interface.

Unified Modeling Language (UML) "Provide the development community with a stable and
common design language that could be used to develop and build computer applications" (bell.2003) In this
report, we use three types of UML models, which are:
Use case diagram: "A use case illustrates a unit of functionality provided by the system the main
purpose of the use-case diagram is to help development teams visualize the functional requirements of a
system, including the relationship of "actors" (human beings who will interact with the system) to essential
processes, as well as the relationships among different use cases.
Activity diagram: "Activity diagrams show the procedural flow of control between two or more
class objects while processing an activity.
Entity Relationships Diagram: "is used for describing data and the relationship between different
entities in a database. It creates a visual map outlining process requirements and detailing connections
among entities and their attributes.
Block Diagram: a high-level diagram used in engineering too. It’s also used to create new systems
or improving an existing system.
