GSM BASED ANTI THEFT SYSTEM FOR VEHICLES conclusion In a situation where there is high level of theft, there is need for better security system. It is much safer to have a System that monitors and communicates to the device owner. This tends to utilize the availability of GSM network, mobile phone and electronics circuit to achieve an automated system which is programmed to work as a thinking device to accomplish this purpose. Global system for mobile communication (GSM) is a wide area wireless communications system that uses digital radio transmission to provide voice, data, and multimedia communication services. A GSM system coordinates the communication between a mobile telephones (mobile stations), base stations (cell sites), and switching systems. . The power supply provides the voltage and current required for effective performance of the system. This supply is tapped from the car battery and then regulated before being fed to the system. i. If the system is active, it monitors both the car doors and boot to check if anyone is opened. ii. Demobilizes the car by disconnecting the ignition line from the battery supply via the actuator . iii. Sends text message to the car owner signifying where the attempt is made from, and finally iv. Starts up an alarm for alert purpose. GSM based Anti-theft system implemented on 8051 microcontroller. This is a very useful application of GSM (Group Special Mobile) and is very commonly used in vehicles. A GSM system consists of a modem. The modem acts as a modulator and demodulator for GSM signals. The relevant messages are also displayed on a computer screen.

3. INTRODUCTION
In a situation where there is high level of theft, there is
need for better security system.
It is much safer to have a System that monitors and
communicates to the device owner.
This tends to utilize the availability of GSM network,
mobile phone and electronics circuit to achieve an
automated system which is programmed to work as a
thinking device to accomplish this purpose.

5. WORKING
 Global system for mobile communication (GSM) is a wide area
wireless communications system that uses digital radio
transmission to provide voice, data, and multimedia
communication services. A GSM system coordinates the
communication between a mobile telephones (mobile
stations), base stations (cell sites), and switching systems.

6. . The power supply provides the voltage and current
required for effective performance of the system. This
supply is tapped from the car battery and then regulated
before being fed to the system.

7. i. If the system is active, it monitors both the car doors and boot
to check if anyone is opened.
ii. Demobilizes the car by disconnecting the ignition line from
the battery supply via the actuator .
iii. Sends text message to the car owner signifying where the
attempt is made from, and finally
iv. Starts up an alarm for alert purpose.

8. APPLICATION
 Vehicles
 Home Security
 Security of commercial bodies.

9. FUTURE SCOPE
 Cameras can be added to identify person responsible.
 GPS system can be added to keep the track of the stolen
vehicle.

10. ADVANTAGES
 Secure vehicles.
 Low cost security system for vehicles.
 Highly reliable.

11. CONCLUSION
GSM based Anti-theft system implemented on
8051 microcontroller. This is a very useful application of GSM
(Group Special Mobile) and is very commonly used in
vehicles. A GSM system consists of a modem. The modem
acts as a modulator and demodulator for GSM signals. The
relevant messages are also displayed on a computer screen.
