ACKNOWLEDGEMENT
We present with immense pleasure the report on MOBILE PHONE DETECTOR We would like to express our immense gratitude to all those people from whom we have got considerable support and encouragement during this project. Many people helped, provided direction, technical information and advice at all stages of the project and it’s our pleasure to thank them all. We are very thankful to our college Shri S’ad Vidya Mandal Institute of Technology, which provides us such a good environment and facilities. We are also thankful to the Head of Department Prof. Meghna A.Vaghela for providing us the opportunity and all the necessary facilities, help and support. However with the help of our project guide Prof. Patel Dhaval A. it seems much more of our interest diverted in doing the project then we expected. During every visit to the guide, we obtained lot of encouragement as well as support.

Abstract
This handy, pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile cell phone from a distance of one and-a-half meters. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc. It is also useful for detecting the use of mobile phone for Spying and unauthorized video transmission. The circuit can detect the incoming and outgoing calls, SMS and video transmission even if the mobile phone is kept in the silent mode. The moment the Bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks. The alarm cont inues until the signal transmis sion ceases. Assemble the circuit on a general purpose PCB as compact as possible and enclose in a small box like junk mobile case. As mentioned earlier, capacitor C3 should have a lead length of 18 mm with lead spacing of 8 mm. Carefully solder the capacitor in standing position with equal spacing of the leads. The response can be optimized by trimming the lead length of C3 for the desired frequency. You may use a shot telescopic type antenna. Use the miniature 12V battery of a remote control and a small buzzer to make the gadget pocket-size. The unit will give the waning indication if someone uses Mobile phone within a radius of 1.5 meters.

Introduction
As increase in the technology in the world using the electronic equipments are being used in a wrong way like, in the examination halls and confidential rooms. To avoid this we are introducing a project called CELLPHONE DETECTO
This handy, pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile cell phone from a distance of one and-a-half meters. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc It is also useful for detecting the use of mobile phone for Spying and unauthorized video transmission. The circuit can detect the incoming and outgoing calls, SMS and video transmission even if the mobile phone is kept in the silent mode. The moment the Bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks. The alarm continues until the signal transmission ceases.

Story boarding
Happy story :
When we try to find are design engineering 2A topic we are walking way to railway station and someone say my phone is missing and there are too dark to find mobile that time someone say if we have mobile phone detector device we find the mobile after this incident we decide we make the mobile phone detector.

Sad story :
For Design engineering 2A we try to find are topic title but in class there is no network in lab are network is on 2G network so we can’t suffering the internet and by this we can’t find topic title and so we late for the registration process.

Circuit working
One lead of the capacitor gets DC from the positive rail and the other lead goes to the negative input of ICI. So the capacitor gets energy for storage. This energy is applied to the inputs of IC1 so that the inputs of IC are almost balanced with 14 volts. In this state output is zero. But at any time IC can give a high output if a small current is induced to its inputs. There a natural electromagnetic field around the capacitor caused by the 50Hz from electrical wiring. When the mobile phone radiates high energy pulsations, capacitor oscillates and release energy in the inputs of IC. This oscillation is indicated by the flashing of the LED and beeping of Buzzer. In short, capacitor carries energy and s in an electromagnetic field. So a slight change in field caused by the RF from phone will disturb the field and forces the capacitor to release energy
Conclusion :-
This Pocket size mobile transmission detector or sniffer can sense the presence of an activated mobile cell phone from a distance of one and a half meters. So it can be used to prevent use of mobile phones in examination halls, confidential rooms, etc. It is also useful for detecting the use of mobile phone for spying and unauthorized video transmission.
