1.1 Background of Study
term “Smart Home” was first coined by the American Association of House
builders in 1984 with the invention of microcontrollers (Moawia Yahia, 2014).
The overall idea is to provide improved efficiency and security in their place
and areas of applications.
Smart Home can be also known as
Automated Home or intelligent home which indicates the automation of daily
tasks with electrical appliances used in homes. This could be the control of
lights, fans, viewing of the house interiors for surveillance purposes or
giving the alarm alteration or indication in case of gas leakage.
One of the reasons for the rise of
the smart home is the increasing risk of burglary and robbery and the busy
lifestyle of people is leading to the necessity of controlling the devices at
home remotely and increasing the necessity of keeping surveillance over their
The goal of the project is to
implement a smart home system by controlling the electronic devices at home
remotely with the help of a mobile device and getting alerts on intrusion or
movement around the restricted premises.
Arduino- uno Microcontroller, motion
sensors, heat sensors led bulb and SIM808-GPRS/GSM module are used to design
SIM808-GPRS/GSM module and the
Arduino-Uno Board are used to communicate between the mobile phone and the
devices and sensors installed at home. The mobile phone can be used as a
controller from anywhere in the world if the GSM network is available
Lifestyle in the modern society along with human behaviour and
thinking is changing dramatically with the advancement of technology, and the
concept of a simple home is changing into a smart home.
In the scope of industrialization, automation is step beyond mechanization.
Whereas mechanization provided human operators with machinery to assist them
with the muscular requirement of work, automation greatly decreases the need
for human sensory and mental requirements as well. Automation plays an
increasing important role in the world economy and in daily experience.
Automatic systems are being preferred over manual systems. This project shows
the automatic control of a house as a result of which power is saved to some
security has changed a lot from the last century and will be changing in coming
years. Security is an important aspect or feature in the smart home
applications. The new and emerging concept of smart homes offers a comfortable,
convenient, and safe environment for occupants. Conventional security systems
keep homeowners, and their property, safe from intruders by giving the
indication in terms of alarm. However, a smart home security system offers many
more benefits (Mior, 2009).
The advancement of technology has increased the safety and security
of people along with their belongings.
Mobile phones today are not just used to make calls. The use of
mobile phones is changing with the development of technology and they can be
used for different purposes. They can be used as clocks, calendars or controllers
instead of being used just as phones. Today smart phones are available in the
market with different applications and hardware which can be implemented
without any further development or enhancement. With the help of the GSM
network, a mobile can be used to implement a smart home by controlling devices
and getting alerts on robbery and burglary.
The cost of the system can be deter-mined by the user as the cost
depends on the hardware used in the system chosen by the developer.
project consists of a LED light which is controlled by the mobile phone to show
the demo of controlling mechanism of the household devices such as light, fan
or television. In addition, three sensors are used as a heat detector, motion
detector and intrusion detector which trigger the alarm upon reaching the
critical limit. It also consists of a designed
control system which is based on the GSM technology that effectively allows
control from a remote area to the desired location.
This system is also designed to be
able to send information without using a PC (Personal Computer), which helps
monitor the situation the house quickly and cheaply. C programming language is
used in making this system, the program was applied to create a security system
works automatically, which can make two way communications with user mobile
phone when there is a security breach in the house. The two way communication
used to turn off the buzzer after activated when security breach occur.
Modular-in design is use to make easy expandable for more sensors to be added
to the core system - Arduino Uno open-source microcontroller platform (Subash, 2013).
capability on detecting motion with a simple design at lowest cost is needed to
build an effective house security system based on motion detection.
system is limited to areas with GSM network available and the whole system does
not work without the network.
Statement of Problem
in Nigeria is a huge problem, and as such home and personal security threats
are something that all Nigerians experience on a daily basis.
homes, businesses and people spend a significant amount of money on security
fees and systems, many problems and weaknesses still exist within the systems
that we use today.
A residence without a home security
system is approximately three times more likely to be broken into than one
without. Home owners who have home security systems loose less in valuables in
the event of a robbery. These facts prove that the installation of a home
security system dissuades intruders and protects your home.
Thus, having a smart home system may
decrease the chances of a burglary.
Even if the alarm system does not keep a
burglar from breaking in, it may cause the burglar to stay a shorter amount of
Besides the existing alarm is a
dependent system which depends on the neighbours to inform the authority or the
owner about any incident regarding the house. The importance to design a GSM
based smart home system is to have a
more independent device which when it detects any movement especially
human movement, it will send an alert to the home owner and also signal to the
buzzer and timer will set time for period to trigger the alarm.
1.3 Aim and Objectives of Study
The aim of this project is to develop GSM based smart home system
that will allow its users to remotely control and monitor multiple home
appliances and detect intrusion using a cellular phone. (But are not limited
to) security systems, lights; anything with an electrical interface.
The objectives include;
1. To design a GSM smart system for home control
2. To implement the system using appropriate tools
1.4 Scope of the Project
This project concentrates on a
development of a smart home system to control appliances and also detect
intruders in a home. To develop the whole project, it consists of three methods
which the mobile station, the microcontroller unit with the SIM808-GPRS/GSM
module, sensors and the light system and the software programming. Arduino Uno
Board is used as the microcontroller board. The mobile phone is used as a
controller to send instructions and as a recipient to receive the responses and
alerts from the microcontroller unit, whereas the Arduino Board is the unit
responsible for controlling the different parts and acts as the brain of the
system. The SIM808-GPRS/GSM module is responsible for communication between the
microcontroller unit and the mobile station. While the software programming is
based on the microcontroller instruction sets. It contains a program in C
language designed for a security system as an interaction to operate the
