Cell Phone Detector | Circuit Diagram Here is a very interesting and useful project of a sensitive cell phone detector circuit or we can also say it cell phone finder, sniffer or calling detector. The circuit is able to detect a cell phone from more than 10 feet away. The circuit can be used for a variety of purposes, for example it can be use to. Cell Phone Detector. Cell Phone Detector circuit diagram Electronic Circuit The transmission frequency of mobile phones ranges from 0.9 to 3 GHz with a wavelength of 3.3 to 10 cm. So a circuit detecting gigahertz signals is required for a mobile bug. Here the circuit uses a 0.22μF disk capacitor (C3) to capture the RF signals from the mobile phone. Cell Phone Detector Circuit Using LM358 Block Diagram ... Cell Phone Detector Circuit Using LM358 Block Diagram Working and Applications is the artlcle explaining Cell Phone Detector Circuit Using LM358 This Cell Phone Detector which can sense about 4 to 5 meters of distance from activated mobile ... Hidden Active Cell Phone Detector Circuit and ... ElProCus Hidden Active Cell Phone Detector Circuit The transmission frequency of cell phones ranges from 0.9Hz 3GHz with a 3.3cm 10cm wavelength. RF signals can be collected from the cell phone along with the disk capacitor and the leads which acts as a small gigahertz loop antenna. Mobile cell phone detector (sniffer) circuit diagram ... Working mobile detector. The circuit is able to detect all forms of mobile phone activity even when it is in silent mode. The circuit is designed as a sensitive RF detector. The RF signal diode 1N3491 forms the major element. With the help of a resistor and a capacitor the signal diode picks up the RF energy in the area. In the standby mode,... Mobile Phone Detector Using LM358 | Full Electronics Project Circuit and working. Circuit diagram of the mobile phone detector using LM358 is shown in Fig. 2. It is built around LM358 (IC1) and npn transistor BC548 (T1). When a mobile phone is active, it radiates RF signal that passes through nearby space. The signal contains electromagnetic RF radiation from the phone. Project report of Cell phone detector circuit slideshare.net Project report of Cell phone detector circuit 1. CELL PHONE DETECTOR PROJECT REPORT OPERATIONAL AMPLIFIERS & OSCILLATORS `GROUP MEMBERS Mohsin Meraj 2012 EE 313 Shaheryar Farrukh 2012 EE 314 Hafiz S.M Rasheed 2012 EE 325 Moin Aman 2012 EE 336 Submitted to: Miss Sabeen Long Range Cell Phone Detector | Circuit Diagram Here is a very sensitive long distance cell phone detector circuit that can detect the mobile phone signals from 30 to 40 feet away. It is a very useful circuit and can be used to detect cell phones at the places where they are not allowed for example examination halls etc. How To Make Cell Phone Detector Circuit on A Breadboard The following circuit diagram shows the cell phone detector using a breadboard. In this circuit to detect the incoming & outgoing signals of a cell phone, we are using CA3130 op amp IC. The op amp noninverting end is connected to the Vcc with the help of 2.2M resistor. The op amp is also connected to the ground through 100K and 100µF capacitor.
