With the development of communication technology the requirement of cellphones has expanded dramatically. In this article we are going to make a cell phone detector circuit that will sense the presence of a cell phone in the surrounding by the detection of these frequencies. The pocket-sized cell phone detector can detect the hidden active cell phone.
This project is cool to play with and very useful to teachers so that they can find the students who are using cellphone inside class room. This is a very useful device in modern time whenever unwanted activities are growing due to cell phone. The Berkeley Varitronics systems Wolfhound cell phone detects Personal Computers.
The circuit which is created is an OP-AMP circuit which is done be IC LM358IC. 22M Ohm Resistors x2. Now we will make a handy cell phone detector which is able to detect active cell phones near by this circuit.
These circuits are designed in such a way that it rectifies low signal frequencies with very low noise of rate. We will discuss both of the circuits here one by one. So IC2 will be also off.
It is a close range cell phone scanner than scans concealed cell phones even when they are off and their battery is removed. A cellphone generally transmits and receives indicators in the frequency range of 09 to 3GHz. A simple cell phone detector circuit can be made in two ways.
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. Choice Based Credit System CBCS SYLLABUS OF COURSES TO BE OFFERED Core Courses Elective Courses Ability Enhancement Courses. By DADI TIRUMALA TARUN.
This mobile phone detector can sense the presence of an activated mobile phone from a distance of four to five metres. When the signal is detected an LED blinks to indicate the usage of a cell phone within a radius of 15 metres. The circuit can detect incoming and outgoing calls SMSes Internet and video transmissions even if a mobile phone is kept in silent mode.
The best use of this cellphone detector is in examination hall meeting rooms etc. A Project Report at CELL PHONE DETECTOR Submitted by. Components Required for Cell Phone detector.
As the cell phone sends or receives a message or call it sends off a signal. As it is said before the two ways two make a cell phone detector circuit include a. Cell phone detector or mobile sensor is a very helpful project in sensing presence of switch-on mobile within range of 15 meters.
Basically Cell-phone detector is a Frequency Detector or a Current to Voltage Converter Circuit which catches frequencies about 08 - 30GHz Mobile band frequencies. 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. 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.
This signal is detected by our circuit and will cause the LED to blink and buzzer to sound. A Project Report at CELL PHONE DETECTOR. Cell phone detector Normally IC1 is off.
Principle of Mobile phone detector. The project made is a cell phone detector which is capable of detecting the 2g3g4g cell phones and its signals. Basically Cell-phone detector is a Frequency Detector or a Current to Voltage Converter Circuit.
A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell phone when in use. 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. Its small size makes it handy and it easily occupy space in your pocket.
RL tuned circuit ResistorInductor. When the power is switched on as stated above IC1 will give a high output and T1 conducts to trigger LED and Buzzer This can be a good indication for the working of the circuit. The basic principle of cell phone or mobile detector is to detect the RF signal frequencies.
When the signal is detected an LED blinks to indicate the usage of a cell phone within a radius of 15 metres. A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell phone when in use. Here is a simple engineering project namely the hidden active cell phone detector.
A cell phone detector is a device which detects any cell phone at any examination hallmeetings and any other place whenever required. 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. This cell phone detector can also be called as mobile phone detector or smartphone detector.
Manta Ray Cell Phone Detector The Manta Ray cell phone detector is manufactured by Berkeley Varitronics Systems in the Unites States of America USA.
