This document describes a border security and alert system using GSM technology. The system uses an LPC2148 microcontroller interfaced with IR sensors, a GSM modem, buzzer, and LCD to detect intruders and alert authorized personnel via text message. When an IR sensor detects an object at the border, the microcontroller sends an SMS via the GSM modem. The system provides low-cost border security automation and real-time intruder alerts to remote users through standard mobile networks and devices. Potential applications include defense, banking security, and museum protection.

3. INTRODUCTION
There is a lot of requirement to automate the security
systems to ensure the security of the boarders at low cost.
In our project we are going to develop an embedded
security system which will detect the others not to intrude
our boarders The security system will use gsm interface to
inform the authorized person.

4. Border Automation
(Case Study)
Why we need it…..?
 We need it for protecting our border
and alerting us if any intruder comes
into our borders
 Needs arising to operate devices
and protect us 24/7 while we are
not able to access physically all
the time
4
Implementation……
 Devices are connected to an
embedded system.
 The embedded system is
programmed to control the devices
according to commands given and
used to sense accordingly and
alerting us via message to mobile at
remote area

Microcontroller

8. RPS (Regulated Power Supply)
To convert high AC main to low volt
supply for electronic circuits
A DC supply which maintain output
voltage constant irrespective of a.c
mains fluctuations

9. IR Sensor…
 An IR sensor is an electronic instrument that is used to sense
certain characteristics of its surrounding by either emitting
infrared radiation
 Infrared Sensors are a type of motion sensor that emit a signal,
and detect the signal or reading reflections received in their path
9

10.  IR Sensor detects the things moving around with in its path
The average value, as the detection range is between 8m to
12m. Here we are using 2 ir sensors node 1 and 2
respectively whenever an object comes into its path it detects
and send signal to microcontroller that at particular pt object
is detected

11. Buzzer
 A buzzer is nothing but a device which
is used to give up a ring or an alarm when
required by the object.
 In our project buzzer is used to find out
the intruder and it is also used to give a
signal to the user by giving an alarm

12. LCD
 LCD consists of Two Glass Plates With Liquid Crystal
Material & Sand Witched In Between Them The Inner Surface
Define Characters
 In our project we are using 16x2 display for viewing

13. Gsm Module
 GSM means a global system for mobile communication
 A GSM module is a device which accepts a sim card and operates
over a subscription to a mobile operator just like a mobile phone .
 GSM modems are frequently used to provide internet
connectivity & sending or receiving sms or mms messages

14. 14INTERFACING GSM TO
LPC2148
GSM modem interfacing with microcontroller via MAX232 for
SMS control The sending SMS through GSM modem when
interfaced with microcontroller or PC is much simpler because as
the conversion of code or data is done by max232

15. OVERVIEW 15

16. Pros
 Circuit is inexpensive & highly secure electronic
system.
 Low power consumption
 Easy set up & wiring connection.
16

17. APPLICATIONS
 This system is used in banks and other security areas.
 This can be used in defense applications to detect the humans
in war field.
 This can be used in the museums to protect the valuable
things.

18. SCOPE
 The scope of our project “GSM Based control system” is
immense the future implications of the project are very
great considering the amount of time and resources it saves.
 The project we have undertaken can be used as a reference
and can be used to develop project such as indicating
weather forecasting, temperature updates, device
synchronization, & also in industries , schools etc

19. CONCLUSION
In this Era when the number of person or intruders
growing at a high rate, this system makes use of the
mobile networks to provide the users with a simple and
cheap & also a very quick and safe border Automation
System and also helpful in security and safety a bit
ahead
