The document presents a touch pad interfaced GSM-based security system aimed at enhancing security through GSM technology, which is widely available and reliable. It details the working of the system, which includes a numeric touch pad for user authentication, and the role of a microcontroller in processing access codes and sending alerts in case of unauthorized attempts. Key components required for implementing this system, such as motor drivers and GSM modules, are also outlined.

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
