Overview of cell phone detector 2. Cell phone detector project ppt.
Cell Phone Detector Project Report. 10494660-tiny AVR microcontroller Projects for Evil the Genius. Cell phone detector is an electronic device used to detect mobile phones almost everywhere in the range of the device.
The construction of this pocket size mobile phone signal detector is so simple and not expensive. The Schottky Diode is used to detect the mobile phone signal in the Schottky diode circuit because it has the unique attribute of being able to correct low frequency signals with low noise rate. CELL PHONE DETECTOR.
A circuit that detects signals of the range 09GHz to 3GHz is used to detect a cell phone when in use. While people have to be connected to one another there are situations or places where there usage is to be prohibited either due to security reasons or it may cause health hazards. The Cell Phone Detector circuits work on the premise of detecting RF signals.
Circuit diagram of the mobile phone detector using LM358 is shown in Fig. To avoid this we are introducing a project called hidden active cell phone detector. Cell Phone Detector Project Report.
The lead length of the capacitor is fixed as 18 mm with a spacing of 8 mm between the leads to get the desired frequency. Printed circuit board pcb construction 6. AJAY GUPTA AJAY KUMAR CHOMAL ANKUR MAHALA.
Viii ABSTRACT Cell phones are widely used in the world. Mobile phone detector pdf 1. Cell phone detector project report.
The Op-Amp part of the circuit acts as the RF signal detector while the transistor part of the circuit acts as the indicator. It is built around LM358 IC1 and npn transistor BC548 T1. Overall mobile phone detectors can prevent the use of mobile phones in prisons movie theaters classrooms and in any facility that individuals do not allow cellphone usage.
Working of cell phone detector 5. NE555 IC CA3130 IC BC548 TRANSISTOR. An ordinary RF detector using tuned LC circuits is not suitable for detecting signals in the GHz frequency band used in mobile phones due to the high frequency at which it transmit and huge energy that it gives out 6 Signal Fig1.
Cell phone detection has been on investigation for a long time. When the signal is detected an LED blinks to indicate the usage of a cell phone within a radius of 15 metres. Cell phone detector project pdf.
