In the Schottky diode circuit the Schottky Diode is used to detect the cell phone signal as they have a unique property of being able to rectify low frequency signals with low noise rate.

. 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. As the cell phone sends or receives a message or call it sends off a signal. Mobile Phone Detector is a Circuit that detects the presence of Mobile Phone up to a certain range like 15 meter.

When the circuit detects an RF signal from an activated mobile phone it gives an. The cell phone detectors are mostly hand and pocket-size mobile transmission detectors. This signal is detected by our circuit and will cause the LED to blink and buzzer to sound.

By Student1 Student2 AIM of the project 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 hallsThe major building. So it can be used to prevent use of mobile phones in examination halls confidential rooms etc. The Cell Phone Detector is essentially a Frequency Detector or a Current to Voltage Converter Device which detects frequencies between 08 and 30 GHz Mobile Band Frequencies.

The pocket-sized cell phone detector can detect the hidden active cell phone. The circuit of the cell phone detector can easily know the signals of the incoming and outgoing. This project utilizes the RF system of the cell phone as the feature to be used to detect its presence.

Mobile Phone Detector Circuit. HIDDEN ACTIVE CELLPHONE DETECTOR Under the guidance of Internal guide name. The best use of this cellphone detector is in examination hall meeting rooms etc.

Basic Principle of Mobile Phone Detector Circuit. It detects the phone when an incoming call or outgoing call is made or when an SMS is sent or received or any GPRS used. The basic principle behind the Cell Phone Detector circuits is to detect the RF Signals.

Cell phone detector or mobile sensor is a very helpful project in sensing presence of switch-on mobile within range of 15 meters. Cell Phone Detector - Free download as Powerpoint Presentation ppt PDF File pdf Text File txt or view presentation slides online. It can sense the presence of an activated mobile phone from a distance of one and a half meters.

It can be used to prevent use of mobile phones in examination halls confidential rooms etc. Mobile Bug Cell Phone Detector Ppt Persentation Way2project In. 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.

The Berkeley Varitronics systems Wolfhound cell phone detects Personal Computers. A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell phone when in use. 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.

Its small size makes it handy and it easily occupy space in your pocket. The device can detect the incoming and outgoing calls SMS. When the signal is detected an LED blinks to indicate the usage of a cell phone within a radius of 15 metres.

So this project is used to neglect the use of cell phones in exam halls private rooms defense establishments hospitals military camps petrol pumps and also very useful for sensing the use of mobile phones for spying and other correlated activities. 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 can be used to prevent use of mobile phones in examination halls confidential rooms etc.
