The circuit of Mobile bug can detect the incoming and outgoing calls, SMS and video transmission, even if the mobile phone is kept in the silent mode. The moment the Bug detects RF transmission signal from an activated mobile phone, it starts sounding a beep alarm and the LED blinks and thus the person with mobile phone can be traced easily. Your burglar alarm continues till the transmission transmitting stops. Put together the particular signal using a general intent PCB since stream-lined as you possibly can along with enclose in the tiny field such as rubbish cellular case.
Recommended Project: RF Controlled Spy Robot
As stated previously, capacitor C3 needs a new lead length of 17 mm with lead spacing regarding 8 mm. Carefully solder this capacitor with position placement with identical spacing on the leads. Your reaction may be optimized simply by trimming this lead length of C3 with the sought after rate of recurrence. You could possibly make use of a small telescopic sort antenna.
The prototype version has only limited range of 2 meters. But if a preamplifier stage using JFET or MOSFET transistor is used as an interface between the capacitor and IC, range can be increased. Use this project report for your reference and study work only.
