suppose this security system is fitted in your car . If a thief breaks in and tries to drive away your car then he/she have enter the code for ignition .If the code mismatches then it will send a message to the proprietor's cell "security breach".By this we will come to know that someone is trying to steal your car. "THAT IS THE IDEA OF THE PROJECT"

3. This presentation is all about creating a
logical visualization of our project i.e.,
TOUCH PAD INTERFACED GSM BASED SECURITY
SYSTEM

4. HERE WE GO…

5. INTRODUCTION
• GSM is the well known wireless standard in
present scenario.
• Security solution based on GSM network will
have highest advantage as GSM network is world
wide network.
• 90% company provide GSM network like
AIRTEL, IDEA, VADAFONE. So there are less
chance of network failure.
• So GSM service can be used to detect an
intrusion.

7. WORKING:-
• Numeric touch pad is interfaced with port of the
microcontroller.
• User has to enter the security code using numeric
touch pad.
• Access will be given three time for individual user.
• If any unknown person try to access the code
after three times immediately message will be
sent to the authorized person regarding illegal
access.

8. Contd…
• Microcontroller is the brain of any embedded
system.
• Microcontroller is a Microprocessor and a
dozen other functions in single chip
• Microcontroller takes in the password from
the person to be authenticated.

9. Contd…
• Motor Driver IC’s are used to interface the
motors with microcontroller.
• Multiple motors can be used to open or close
multiple doors.

10. Contd…
• GSM is used to send the message or to ring
the authorized person regarding the intrusion.
• GSM works on UART protocol of micro
controller
