That’s Why we can practice it to avoid using mobile phones in meetings, office time, examination halls, private rooms, etc.

Components:

  • 2 Mega Ohm resistor (2)
  • 47 Pico Farad capacitor
  • 22 Micro farad capacitor
  • CA3130 IC
  • BC548 Transistor
  • LED
  • 100 micro farad capacitor
  • 9v Battery with clip
  • (100 & 1) k ohm resistor

Working:

This instant when the bug detects RF communication signal from a started mobile phone, alarm is activated and also the LED blinks. The alarm continuously beeping until the signal transmission stops.

Large Level Use:

It is very useful for detecting the use of mobile phone for undercover work (spying) and un-official video transmission. Many other places where use of mobile phones is not acceptable like Official meetings, exam halls, temples, offices and theaters, from those places to sense and control the use of cell phones this planned structure is very helpful. it must be detecting the incoming & outgoing calls, messages and video communication even if the cell phone is kept in the quiet mode.
