What is Mobile Phone Detector?
We are well familiar with mobile phone active detectors. The cell phone detectors are mostly hand and small-size mobile transmission signal detectors. It can observe the activated cell phone from a distance of one or half meters. 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
Circuit Diagram:
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.
Small Level Use:
- Mobile Phone Detector is used to detect a hide cell phone in class room
- This Is Helpful used to detect cell phone in office times.
- It is used to detect cell phone in Exams hall.
- It also detects the incoming and outgoing calls, Messages and video communication even if the cell phone is kept in the silent mode
- These devices are important hazard to prison security and avoid the monitoring procedures in jails, while helping prisoners commit new crimes both inside and outside the facility.
