2. Itroduction To Our Project
Detection of the presence of \cell phone in areas where usage of cell phone is prohibited

3. OVERVIEW This is a handy pocket-size mobile transmission detector .
It can sense the presence of mobile phone.
This circuit can detect incoming, outgoing calls, sms, video transmission even if the phone is in silent mode.
Moreover, it can detect the presence of mobile phones in switched condition via EMF.

4. MOTIVATION It can be used in our day to day life conveniently
It has to be cost effective that means using affordable materials in an effective way
It should provide optimum efficacy

7. Functionality
Powered objects as cell phones give off electromagnetic energy when a current flows. So ,If we can detect the EMF, we will be able to detect the phone without any activity.
electromagnetism occurs when electric current changes or moves. Stronger currents give off higher EMF readings. Which made possible to detect the cell phone
We will be getting the voltages using a Solid core wire
We have also used LEDS to identify which direction the cell phone is located.

8. APPLICATION College and University. Airplanes Prisons Hospitals
Cinemas & Theaters
Security
