INTRODUCTION
1.0. Introduction
In a situation where there is high level of thief, there is need for better
security system [1]. There is a growing interest in intelligent home network as a
way to offer a comfortable, convenient and safe environment for occupants. In
order to enhance the occupants convenient and safety, home security system is
important in the field of intelligent home network. The requirements of a home
security system include low cost, low power consumption, easy installation and
rapid response to alarm incident [3].
According to connecting mode, home network can be divided into two
types, which are wireless network and non-wireless network. It’s clear that the
2
wireless technology has some remarkable benefit comparing with non-wireless
technology. Research shows that Bluetooth, Zigbee, 802.11 and wireless USB
are the most popular technology in the field of wireless network. However, the
technology that has been mentioned is high in power consumption, high in cost
and don’t present the implementation.
Is has become more crucial to inform the user in real-time when the alarm
is triggered. Other than the technology that mentioned earlier, it also can be done
via internet or GSM/GPRS. However, GSM is more convenient than the internet.
The main reason why the GSM is more convenient is that the GSM network has
wide spread coverage, making the whole system available for almost all the time,
since GSM is stand for Global System for Mobile Communication. Furthermore,
GSM network has high security infrastructure which make sure that the
information sent/receive cannot be monitored.
Basically GSM stand for Global System for Mobile Communication. In
this project, the GSM modem will be used. GSM modem is a wireless modem
that works with GSM wireless network. A GSM modem is specialized type of
modem which accept SIM card and operates over a subscription to a mobile
operator. The GSM modem comes with a serial interface through which the
modem can be controlled using AT command interface.

Figure 1.0: Block Diagram of the Project
GSM is a digital mobile phone system, operating in several frequency
bands. Most knowing bands are 900MHz, frequencies, 1800MHz but also in the
bands of 1900MHz and 2100MHz depends on their memory cards called SIM
(Subscriber Identity Module), which provide user identity to network with their
telephone number assign [2]. GSM provide the highest quality data calls, and
moreover, offer the possibility of using the same mobile phone (with the same
SIM card, and hence the same number) and other network around the world
(roaming) so that the user can be found even if it is not in the country. The GSM
itself consist of the interconnected cell. Each cell corresponds to a specific
antenna (base station), placed on towers or tall building to avoid a nearimmediate access to their public persons.
For this project, the working principle of the GSM is used to send the
message/notification to notice the owner that their premise/home/shop/office has
an intruder/theft. As in this project, the GSM modem is used together with the
microcontroller PIC16F877A to act as a security alarm. The LCD is used to
display the warning signal when the alarm is triggered.
4
To detect any activity such as open door/window, the reed sensor is used.
This project will help the alarm systems exist today more efficient since the
user/owner can get the notification immediately as the reed sensor is triggered
simultaneously with LCD display by the microprocessor. Not only that, by
display the warning signal using the LCD display, people surrounding will notice
immediately which house/premise has an intruder. This is the important of this
project which it is affordable to most people. People will not only can hear, but
also can see the warning signal. This is the adding value of this product because
it helps people with hearing problem to contribute/take action when he/she are at
the incident site.
After some research, the reed sensor is the best sensor that can be used
for this project. There are many sensors that can be used such as PIR sensor, but
research finding that reed sensor is more suitable since it can act as a switch.
This magnetic switch is employed as magnet-sensitive contactless bi-stable limit
switch. More about this sensor will be discuss in Chapter 3.

1.1. Objective
The aim of this project is;
i.
To send the notification to the owner.
It becomes more crucial to inform the user in real-time when the alarm
system is triggered. By using the GSM modem, the notification /message
can be sent to the user when the alarm system is triggered. When the
sensor detects the intruder/theft, it sends the data to the processor to
process information, and send message to the owner via GSM modem.
User will get the message through the phone.
ii.
To display the warning signal
The adding value on this product is the LCD display. This will make
people more aware about the current incident. Not only that, people with
hearing problems can also react with the situation because she/he can see
the warning signal from the LCD. This product will not only send the
message to the user, the warning signal also is displayed through the LCD
display. This LCD display is placed at outside of the premise/home. By
display it, the people at surrounding can see easily where that sign is
come from. So the information can transfer smoothly.
iii.
To make the security alarm more efficient.
By display the warning signal and sent the notification message to the
owner, this project can make the alarm systems exist nowadays more
efficient.
6
1.2. Problem Statement
The security systems nowadays are too expensive to most people that
have middle income. Research find that for ADT alarm, the moderate cost is
around RM900.00 and above. Next, security alarm that exists also can’t make the
people on surrounding to be aware to that warning sound. People sometimes
would get confused to detect the exact location of that warning sound. Not only
that, in real world, when the alarm system is triggered, people will automatically
assume that the alarm system is broken or is being fixed by the user. At this
point, it can be seen the alarm system that exist today not efficient in term of
information transfer. The most important things is, today alarm system failed to
inform the owner about the incident. Try to guess what happen when the alarm
system is triggered at midnight? There will be no people surrounding to react
with the situation. This problem becomes more serious when come to public
holiday, such as Hari Raya where most of people will back to their hometown for
a several days. The user will not notice it until the time he/she come to
premise/home. This make the alarm system is not efficient enough.
Therefore, to overcome these problems, GSM Based Display Toolkit:
Alarm systems are introduced. These systems will give the notification message
to the owner immediately once the alarm is triggered. Not only that, it also will
display the warning signal at the LCD display so that people around will notice it
immediately. By display the warning signal and give the notification to the
owner, this project will produce one more alarm systems that is more efficient
since people with hearing problems can also react with the situation. Not only
that, people also can know exact location of the incident because this product
will display the location of the switch triggered at the LCD display. For example,
when switch 1 that is located at the back door of the premise/house/shop is
triggered, the LCD will display “Warning, intruder on back door”. The
information transfer also can be delivered smoothly and efficiently.
7
1.3. Scope of Work
The aim of this project is to send the notification to the owner
simultaneously by display the warning signal through LCD display. To make this
project work as mention, both hardware and software are needed. The software
that will be used in this project is CCS Compiler and Proteus. All the program
code will be design in the CCS Compiler. The circuit is design inside the Proteus
software. So, to test whether the program code that has been design is work or
not, the program code is then transfer into the processor in the Proteus software.
Then, to get the desired result, run the circuit. This both software are depends to
each other.
For the hardware, this project will need microcontroller PIC16F877A,
Magnetic switch sensor, GSM modem, mobile phone and LCD with 2x16 lines.
The magnetic switch sensor will detect any movement for door/window. When
the switch is triggered, the processor will process the data, and then give the
output such as display the warning signal using the LCD display, and send the
message to the owner through GSM modem and the owner will display it
through mobile phone.

When the system consist of hardware and software function properly, the
model for the project is then can be design. Below is the design of the model.

with the situation. This problem becomes more serious when come to public
holiday, such as Hari Raya where most of people will back to their hometown for
a several days. The user will not notice it until the time he/she come to
premise/home. This make the alarm system is not efficient enough.
Therefore, to overcome these problems, GSM Based Display Toolkit:
Alarm systems are introduced. These systems will give the notification message
to the owner immediately once the alarm is triggered. Not only that, it also will
display the warning signal at the LCD display so that people around will notice it
immediately. By display the warning signal and give the notification to the
owner, this project will produce one more alarm systems that is more efficient
since people with hearing problems can also react with the situation. Not only
that, people also can know exact location of the incident because this product
will display the location of the switch triggered at the LCD display. For example,
when switch 1 that is located at the back door of the premise/house/shop is
triggered, the LCD will display “Warning, intruder on back door”. The
information transfer also can be delivered smoothly and efficiently.

1.3. Scope of Work
The aim of this project is to send the notification to the owner
simultaneously by display the warning signal through LCD display. To make this
project work as mention, both hardware and software are needed. The software
that will be used in this project is CCS Compiler and Proteus. All the program
code will be design in the CCS Compiler. The circuit is design inside the Proteus
software. So, to test whether the program code that has been design is work or
not, the program code is then transfer into the processor in the Proteus software.
Then, to get the desired result, run the circuit. This both software are depends to
each other.
For the hardware, this project will need microcontroller PIC16F877A,
Magnetic switch sensor, GSM modem, mobile phone and LCD with 2x16 lines.
The magnetic switch sensor will detect any movement for door/window. When
the switch is triggered, the processor will process the data, and then give the
output such as display the warning signal using the LCD display, and send the
message to the owner through GSM modem and the owner will display it
through mobile phone.

When the system consist of hardware and software function properly, the
model for the project is then can be design. Below is the design of the model.

1.4. Methodology
Figure 1.3: Basic Project Flowchart
This project starts with title confirmation with the supervisor and
submission of the project proposal. After it is clear about the registered title,
some research on background study and literature review is done. This literature
review is the detail about the component that is being used for this project. After
some research, the hardware and software is starting to develop before test the
functionality. During the software and hardware development, this stage will
consume more time since this stage will determine the functionality of the
