Introduction: CELL PHONE DETECTOR

About: electronics and technology

When thinking about cellphone jammer i got a idea of making a circuit which is capable of detecting the phone's call and message. it may be incoming or out going

The project made is a cell phone detector which is capable of detecting the 2g,3g,4g cell phones and its signals

the circuit which is created is an OP-AMP circuit which is done be IC LM358IC

this project is cool to play with and very useful to teachers so that they can find the student's who are using cellphone inside class room

Step 1: Watch My Youtube Video for Better Clarity

Step 2: Get the Components

LM358 ic

6.8m resistors

0.1uf capacotors

breadboard

500k potentiometer

connecting wires

LED

Bread Board: http://amzn.to/2jtZxH3
Collection Box(includes all): http://amzn.to/2BXEXGI

IC LM358 : http://amzn.to/2BUVqLH

Connecting Wires: http://amzn.to/2BUVqLH

i have provided link to get the components

Step 3: Check for Connections

CHECK IT OUT GUYS I HAVE ADDED THE SCHEMATIC DIAGRAM FOR THE CIRCUIT

check the connections from the above image and check the video for further clarity

    Can you give me working principle of this circuit ?

    what is there extra in pdf files..if i upgrade to premium.

    In video only one stage ckt is used,while schematic has 2stages .why?

    Can this circuit, with the exact components used, work for 4G? Because I tried and can’t seem to detect 4G

    Nice, but what's the range ? I have to copy also HowardS31 comment "Nice, but a schematic diagram would be helpful." And why not comment your video instead of putting blow your mind music, it's a little disturbing ! Don't take it bad, I just want to understand better what you made which result is amazing.

    Sure yaar ....I'll make it a better one next time :) .... Thanks for ur review .... I'll provide the schematic diagram soon ...for u guys ..... :)

    Thanks, I'll be waiting for the schematic, keep up the good work, very inventive.

    ya dude thanks i have attached the schematics check it out

    Nice, but a schematic diagram would be helpful.

    Please tell us how far away the phone signal can be detected. Is it only right next to the circuit board?

    Would a better antenna make for a better range?

    Between 5 to 6 meter the circuit can detect the cellphone signals ....and xtend the antenna to longer one to increase the detection range
