3. OBJECTIVE
The objective of this project is to design and develop a wireless
communication link to monitor our organizations that require high
security like Banks , Offices etc.

4. Introduction
• Safety and security of any living or working place is one of the most
primary concerns. Today’s security systems include CCTV surveillance
which are very costly and many of these systems do not trigger any
alarm if intrusion or fire is detected. Thus a cost-effective and fast-
reactive security system is needed.
• For this purpose we have made a prototype of such system which
consists of two sensors- PIR sensor and Ultrasonic sensor; a
microcontroller unit- Arduino Uno board and a SIM900 GSM module.
• If there is intrusion through any of these access points, then the
sensor will detect it, generate pulses to be read by Arduino and then
the procedure similar to that of PIR sensor is followed.

25. GSM MODEM
• GSM Modem is a multi-functional, ready to use,
rugged unit that can be embedded or plugged into
any application.
• The Modem can be controlled and customized to
various levels by using the standard AT commands.

26. GSM MODEM(CONT…)
The modem comprises several interfaces:-
• LED Function including operating Status
• External antenna
• Serial and control link
• Power Supply
• SIM card holder

27. Gsm (cont.)
• The GSM module is connected with the microcontroller through serial
port. Using ‘AT’ commands the SMS is transferred to the GSM
module. The GSM module converts the digital information into
airborne signals. Through GSM network the SMS is transferred to the
required person’s hand phone.
• This system offers better solution for the Bank security system and
also it will help you to track the intruder.

28. Remote Monitoring via Bluetooth Module
• Screenshot for the open source application for sending serial data to
android over Bluetooth.
• Bluetooth Module connected to Rx & Tx Pins of Arduino Sends data to
Paired android Phone .
• User can read the real time log in the serial monitor and also turn off
the alarm from his/her mobile just by sending command.
• Demonstration for the working of application done through the video
provided in zip file.

29. I2C
• The START condition acts as a signal to all connected IC's that
something is about to be transmitted on the bus.
• A STOP condition is sent. This is the signal for all devices on the bus
that the bus is available again (idle).

31. ADVANTAGES
• The status of various devices can be monitored and controlled from
anywhere.
• The operation of the system is very simple and can be used by
anyone with a basic knowledge of operating mobile phones.
• Easy to upgrade as per the user requirement.

32. APPLICATIONS
• Home Automation & Security
• Office Automation & Industrial Automation
• To control water pump sets in agricultural fields.
• The security system can be employed in household
or any organization.

33. LIMITATIONS
• If the main module or the handset is not in the cellular range ,we can’t
control the devices.
• The sensors use RF transmitter and receiver which has limited range, hence
sensors have to be in close vicinity of the main module

34. FUTURE SCOPE OF WORK
• It can be used for high security in banks and other
organizations.
• Connecting More Devices.
• Provision To Store Several Mobile Numbers
• Video Recording Once Alarm Gets Triggered

35. CONCLUSION
• We presented an approach that can be employed to improve the
performance of various devices that are not in the close vicinity of
the user.
• The user was informed about the action through a reply SMS sent
by the modem at the receiver.
