RL tuned circuit ResistorInductor.

. Ravi Kumar 3rb10ec071 Under The Guidance Of. 12 Cellular Phone Technology. This signal is detected by our circuit and will cause the LED to blink and buzzer to sound.

This handy cell phone detector pocket size mobile transmission sniffer can sense the presence of an active cell phone in a radius of 1m-15m. It has made it possible for a person located in a remote-place to communicate with a person across the globe in a fraction of a second. The best use of this cellphone detector is in examination hall meeting rooms etc.

Cell phone detector or mobile sensor is a very helpful project in sensing presence of switch-on mobile within range of 15 meters. Peak-power-output of a mobile-phone correspo nds to 2 Watts with an average of 250 milli-Watts of continuous-power. The cell phone detectors are mostly hand and pocket-size mobile transmission detectors.

It can be used to prevent use of mobile phones in examination halls confidential rooms etc. Its small size makes it handy and it easily occupy space in your pocket. Use of Cell Phone Detector.

Design of a Simple Cell-Phone Radio-Frequency Detector. Amar Raj 3rb08ec007 2. So it can be used to prevent use of mobile phones in examination halls confidential rooms etc.

Most popular mobile phone detectors available under this technology are produced by Berkeley Varitronics Systems and mobile Security products 7 9 These Companies produce the wolfhound cell phone detector and cell buster respectively. As the cell phone sends or receives a message or call it sends off a signal. When the signal is detected an LED blinks to indicate the usage of a cell phone within a radius of 15 metres.

So it can be used to prevent use of mobile phones in examination halls confidential rooms etc. This project utilizes the RF system of the cell phone as the feature to be used to detect its presence. In this project an RF detector using tuned LC circuits is formed for detecting signals in the GHz frequency band used in mobile phones as.

Rishu Raj 3rb09ec060 3. Each hand-set within a cell is allotted a particular -frequency for its use. Therefore the company needs a way to detect cellular phones in the facility.

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. A Project Report at CELL PHONE DETECTOR. Choice Based Credit System CBCS SYLLABUS OF COURSES TO BE OFFERED Core Courses Elective Courses Ability Enhancement Courses.

HIDDEN ACTIVE CELL PHONE DETECTOR. Cellphone signal detector and jammer ppt 1. The device can detect the incoming and outgoing calls SMS even if the mobile phone is kept in the silent mode.

The Berkeley Varitronics systems Wolfhound cell phone detects Personal Computers. It can sense the presence of an activated mobile phone from a distance of one and a half meters. Cell Phone Detector is a circuit that can sense the presence of any activated cell-phone nearby and gives an indication of activated cell-phone near around of it.

So it can be used to prevent use of mobile phones in examination halls confidential rooms. So it can be used to prevent use of mobile phones in examination halls confidential rooms etc. Introduction The main scope of project is to sense the presence of an activated mobile phone from a distance of one-and-a-half meters to prevent the use of same in the examination halls.

However this technology still needs a lot of improvement and development. FUTURE WORK The prototype version has only limited range of 2 meters. A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell phone when in use.

It can be used to prevent use of mobile phones in examination halls confidential rooms etc. INTRODUCTION 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-ahalf meters. A mobile-phone also known as a cellular-phone cell-phone a mobile and a hand-phone is a device that can make and receive phone-calls over a radio-link while moving around a wide-geographic-area.

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-ahalf meters. There are a few existing cellular phone detectors on the market today that could of caught the employee prior to the information leaking out. Aman Kumar 3rb09ec100 4.

A Project Report On Cell Phone RF Signal Detector Jammer Presented By. To avoid this we are introducing a project called CELLPHONE DETECTOR 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.
