This mobile phone detector can sense the presence of an activated mobile phone from a distance of four to five metes . So it can come handy in an examination hall or meetings where mobile phones are not permitted.
The circuit can detect incoming and outgoing calls, SMS, Internet and video transmissions even if a mobile phone is kept in silent mode. When it detects an RF signal from an activated mobile phone, its LED starts blinking and continues to blink until the signal stops.
