Abstract- This system proposes the design and construction of an
advanced car security system using GSM. It uses the GSM
mobile communication networks to transmit alarm signal and
control instruction. The control and communication between the
user and the proposed system are achieved through a short
message services (SMS) protocol available in the mobile phone.
If the car door is illegally opened or the car is vibrated, an alarm
will be activated and it send SMS message to the owner’s mobile
phone immediately and automatically. The user could easily
protect and control their car anywhere at any time. The proposed
system consists both hardware and software parts. The hardware
components include vibration sensors, a PIC microcontroller, a
GSM modem, LCD and buzzer. The software part includes a
program controller interface. PIC MikroC programming
language is used for this control system. The control system is
based on the PIC16F877A microcontroller and AT COMMAND.
Index Terms- GSM Modem, Microcontroller, Vibration sensors,
LCD, Buzzer.
I. INTRODUCTION
output signal arrive at the PIC microcontroller. PIC acts as
electric brain or message sending controller that control all of the
functionality and interfaced circuit attach to the system. It sends
SMS message to the mobile phone via GSM modem. GSM
modem sends the signal (SMS) to the user’s mobile phone when
receive signal from the PIC microcontroller. In this way, the
users can protect from being stolen.
II. PROPOSED SYSTEM
The developed system makes use of an embedded system
based on GSM technology. When an unauthorized person
tampers with a vehicle in which an antitheft system is settled up
then the microcontroller commands the GSM modem to send a
text alert to the vehicle owner. In this system we interfaced
PIC16F877A microcontroller with SIM-com 900 modem to
decode the received message and do the required action. The
protocol used for the communication between the two is AT
command. The commands are standard AT. The PIC
communicates with the modem and a further piece of equipment
using serial protocol.
N
owadays, automobile thefts are increasing as well as
production of cars in yearly world. So, vehicle theft is a
universal problem. To solve this problem, most of the vehicle
owners have started using the theft protection systems. A
wireless vehicle security system which implements mobile
communication protocol is proposed. The most popular existing
car security system is car alarm and has a lot disadvantages. They
are;
Distance- Cover Area, the siren cannot be heard over a
long
distance
Same sound (siren) for most of the cars
False Alarm
Not 100% secure
Cannot be heard in buildings
This type of security system is less effective if the car is far
away from the owner as the alarm cannot be heard by the owner.
So, this paper proposes a car security system using GSM. This
GSM based car security system is an advanced security system.
When the car is vibrated, the system will produces an alarm
signal and immediately send a SMS to car owner’s mobile
phone. The user could easily supervise, protect and control their
car anywhere at any time. The system is divided into three
sections and it was designed using MikroC language. Serial
communication is used for data communication between GSM
modem and PIC16F877A. In this system, firstly, vibration
sensors sense the instruction and produce output signal and these

out to the owner’s mobile phone immediately and automatically
via GSM modem. When receiving a predefined message, the car
owner can know that their car is in a danger condition and take
an immediate action. The proposed system has the following
advantages: low cost, high performance, high security, easy to
implement, and strong security control pattern. In this case, the
driver can leave the car safely.
A. Vibration Sensor
Piezoelectric sensor is used in this security system. It is
generated by pressure on certain crystals which will develop a
potential difference or voltage on the crystal face. When crystal
flexes or vibrates, an AC voltage is produced. A piezoelectric
sensor is modeled as a charge source with a shunt capacitor and
resistor, or as a voltage source with a series capacitor and
resistor.

E. GSM modem
A GSM modem is a specialized type of modem which
accepts a subscriber identity module (SIM) card and operates
over a subscription to a mobile operator just like a mobile phone.
The working of GSM modem is based on commands, the
commands always start with AT (which means ATtention) and
finish with a <CR> character. . In this system, IcomSat v1.1
SIM900 GSM modem is used. The GSM module is communicate
the microcontroller with mobile phones through UART.
F. GSM Technology
it is stands for global system for mobile communication
(GSM). It is widely used mobile communication system in the
world. GSM is an open and digital cellular technology used for
transmitting mobile voice and data services operates at the
850MHz, 900MHz, 1800MHz and 1900MHz frequency bands.

GSM
In this security system, when the car door is locked, the
security system is automatically turned ON. Firstly, the system is
checking the modem and starting the vibration sensor detect the
vibration when the GSM modem response OK. If the sensor is
first detect, the system activate alarm only. When the system
occur second detection during 30 seconds, the system will be
activated alarm and send SMS message to the owner’s GSM.
And a next detection occurs over 30 seconds, the alarm always
turn ON and then it send SMS to the user. In the security system,
it is needed to ground the reset pin for the alarm turn OFF.
III. SIMULATION RESULT
Advanced Car Security System is simulated using PROTEUS
SOFTWARE and their results are presented here. The circuit

measure output result.
