3. 1.ABSTRACT: The need for a concealed weapons and explosive detection systems in uncontrolled environments has increased in recent years. Traditional metal detector inspection systems are limited to controlled environments such as security check points and cannot detect plastic explosives. Civilian and military security personnel need technologies capable of detection of concealed weapons and explosives at remote distances for enhanced safety reasons.

4. 2.OBJECTIVES: Since the main intension of this projects is to design “Metal Detecting and Alerting System Using XBee”. In order to fulfill this application there are few steps that has been performed.

5. 3.BLOCK DIAGRAM :  TRANSMITTER STAGE :

6.  RECEIVER STAGE:

7. 4. METHODOLOGY: The transmitter will have the Metal Detector, when the metal is detected the it gives the signal to the ARM, then the ARM will send the information to another receiving station through XBee which is in Police station or security office. At the same time ARM will generate the out put that is fed to buffer IC 4050,buffer stores and given to the driver IC 2003 in driver current will amplifies and voltage will inverts with the help of Darlington circuit of driver IC to drive the relay. Then signal is given to the output load for indication purpose. When ARM receives the data from the XBee, it will enable the alert through the Buzzer in receiver side.

8. 5. ADVANTAGES & DISADVANTAGES:  ADVANTAGES: 1.More useful in remote areas. 2.Firing events more help full to save. 3.This project we can operate Easily.

9.  DISADVANTAGES: It increases the cost whereas digital systems reduce the cost of system.

10. 6.APPLICATIONS: 1.This project can be implement in Military applications. 2.This project can also use for Landmine detection. 3.This project can be use in Firing situations.

11. 7.CONCLUSION: In this work we have proposed an efficient autonomous system for standoff explosive detection. While comparing with traditional systems have lot of advantages. The main advantages are its miniature size, low power consumption, distributed operation, and easy implementation.
