. Project on CellPhone Detector. Its small size makes it handy. 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.
The transmission-frequency of mobile-phones ranges from 09 to 3 GHz with a wavelength o f 33 to 10. Detectors for all cell phones mobiles and other transmission devices. CONCLUSION This pocket-size mobile transmission detector or sniffer can sense the presence of an activated mobile phone from a distance of one and-a-half meters.
The Zone Protector can be set to alert or notify once a signal is detected. A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell. When a mobile phone is active it.
It is built around LM358 IC1 and npn transistor BC548 T1. HIDDEN ACTIVE CELL PHONE DETECTOR. Working of Cell Phone Detector.
It detects the phone. The cell phone detectors are mostly hand and pocket-size mobile transmission detectors. Design of a Simple Cell-Phone Radio-Frequency Detector.
HIDDEN ACTIVE CELLPHONE DETECTOR Under the guidance of Internal guide name. It can sense the presence of an activated mobile phone from a distance of one and a half meters. Overall the results of this brief-study are potentially-useful as the mobile-phone-transmission-detector can sense the presence of an activated-mobile-cell-phone from a distance of about 4.
Mobile Detector Ppt Final - Free download as Powerpoint Presentation ppt pptx PDF File pdf Text File txt or view presentation slides online. By DADI TIRUMALA TARUN. Circuit diagram of the mobile phone detector using LM358 is shown in Fig.
Cell phone detector or mobile sensor is a very helpful project in sensing presence of switch-on mobile within range of 15 meters. 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. Scribd is the worlds largest social reading and.
Mobile Phone Detector is a Circuit that detects the presence of Mobile Phone up to a certain range like 15 meter. This ppt explains mainly on 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. The cell phone detecting circuit is intended to detect unauthorized use of mobile phones in examination halls confidential rooms prisons etc.
Therefore a circuit detecting gigahertz-sig nals is required for a mobile-phone. Introduction The main scope of project is to sense the presence of an activated mobile phone from a distance of one-and-a-half. By Student1 Student2 AIM of the project The main.
This project utilizes the RF system of the cell phone as the feature to be used to detect its presence. 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. Deploy as a portable or network device.
