3. INTRODUCTION
• Automobile thefts are increasing at an alarming rate all over
the world. So, a security system is the need of the hour.
• Since GSM is reliable and user friendly, so it was a preferable
option for this project.
• GSM-based vehicle anti-theft system development is designed
and developed to improve the performance of the current
vehicle security system.
• Global System for Mobile Communication (GSM) is a good
choice of the communication to replace the conventional
alarm, because it doesn’t require much cost.

4. • The objective of the project is to add an additional feature to
the present security system that will warn the owner of the
vehicle by sending SMS when there has been an intrusion into
the vehicle.

5. • Advance car security system is too expensive. Cost for the
gadget is too high. So, a cheap alternative is the need of the
hour.
• “Remote Car Locking System” is implemented using the GSM
technology.
• The versatility of this technology and the ever presence of the
GSM helps the system to retrieve status of the car, keeping the
car owner at peace.
BACKGROUND

6. MOTIVATION
• As per reports, on an average 1.65 lacs cars were stolen in
India and a bulk of the cars are equipped with pretty basic
security measures or none.
• So, this project would be able to bring in some respite both for
the consumers and the producers. Since the system is
integrated around the engine, so it can’t be accessed by thief
and is quite reliable on both security and alert front with the
GSM technology.
• The system will be able to bring down the numbers of car
thefts and which is the real thrust on working on this project.

7. • Microcontroller AT89S52
• GSM SIM900A
• Valve
HARDWARE USED
Basic Theoretical Notions

8. Microcontroller AT89S52
The AT89S51 is a low-power, high-performance CMOS 8-bit
microcontroller with 4K bytes of in-system programmable Flash
memory.
Features
• 4K Bytes of In-System Programmable (ISP)
Flash Memory
• 4.0V to 5.5V Operating Range
• 128 x 8-bit Internal RAM
• 32 Programmable I/O Lines
• Two 16-bit Timer/Counters

10. GSM SIM900A
GSM SIM900 is a Quad-band GSM engine, which works on
frequencies 850 MHz, 900 MHz, 1800 MHz and 1900 MHz It
is very compact in size and easy to use as plug in GSM
Modem. The Modem is designed with RS232 Level converter
circuitry, which allows you to directly interface PC Serial port.
Features
• High Quality Product
•Quad-Band GSM/GPRS 850/ 900/ 1800/ 1900 MHz
• Built in RS232 Level Converter (MAX3232)
•Configurable baud rate
•SMA connector with GSM L Type Antenna.
•Built in SIM Card holder.

12. Valve
• A valve is a device that regulates, directs or control the flow of
liquid by opening, closing or partially obstructing various
passage ways.
• In open valve, the liquid flows from higher pressure to lower
pressure.
• Here we use valve.

13. SYSTEM DESIGN & DEVELOPMENT
• The system consist of microcontroller AT89S52, GSM
SIM900 and a valve.
• The System basically checks for the status of the ignition lock.
• Whenever the state of ignition lock changes then the status
signal will be send to microcontroller.
• The GSM after receiving the signal sends an alert signal to the
number of the owner.
• When the owner calls then the microcontroller sends the signal
to lock the valve.

14. • Kiel software is been used as it gives the software
development tools for 8051.

18. PROBLEM FORMULATION
• In present security system of the cars, if any intruder
indulges with the locked car, then the system responds
with an alarm basically a high pitch sound to alert
people around.
• If no one is around then the system will be unable to
get the owner’s attention.
• This is where a GSM is required. GSM can help to get
the attention of the owner. A GSM can send SMS to
the owner, which will definitely can get the owner’s
attention.

19. ADVANTAGES
• Better security features.
• Low cost.
• Can’t be accessed from outside
• Car Location Cannot be tracked
.
DISADVANTAGES

20. CONCLUSION & FUTURE
DIRECTION
• This is a unique method of designing and assembling a low-
cost, compact theft control system for an automobile.
• In future, there is no doubt, that all of the vehicles will be
embedded with this unique kit.
The work can be further extended to do the following:
• For Lane Tracking purpose a front camera can be attached to
the vehicle. Long range IR sensors can also be used to avoid
vehicle collision.
• A finger print scanner can be incorporated on the steering

21. wheel of the vehicle to allow only authorized user to access the
vehicle.
• A system for detecting behavior of driver can also be made. A
camera can be placed besides rear view mirror to check the
behavior of the driver.
