- 3. OBJECTIVE The objective ofthis 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 andsecurity 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 • GSMModem 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 modemcomprises several interfaces:- • LED Function including operating Status • External antenna • Serial and control link • Power Supply • SIM card holder
- 27. Gsm (cont.) • TheGSM 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 viaBluetooth 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 STARTcondition 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 statusof 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 themain 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 OFWORK • 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 presentedan 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.
