Introduction: CELL PHONE DETECTOR

Picture of CELL PHONE DETECTOR

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

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 ..... :)

netwjennie (author)xplorelabs2017-12-11

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

xplorelabs (author)netwjennie2017-12-12

ya dude thanks i have attached the schematics check it out

netwjennie (author)xplorelabs2017-12-12

Right on man now you rock! Thank you.

Nice, but a schematic diagram would be helpful.

Sure bro ....I'll make the schematic diagram ...soon for u ...just stay tuned ... To get it ...thanks for the comment :)

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?

xplorelabs (author)wstewl2017-12-11

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

nice brother

does it works on low voltage (ie) voltage less than 9v??

xplorelabs (author)sundarraj raj2017-12-09

yah bro will work .....but not below 5v

xplorelabs (author)sundarraj raj2017-12-09

yah bro it will work ....but below 5v

That's a neat setup :)

xplorelabs (author)Swansong2017-12-09

THANKS BRO

xplorelabs (author)Swansong2017-12-09

thanks a lot bro :)
