Working: The signal power is stored in the capacitor through the wire. The resistor and capacitor connection acts as a filter to select the desired signal (the RF frequency at which the phone operates). The resistor and capacitor value are chosen such that the particular frequency is detected. The operational amplifier amplifies the capture signal because it is too low and a proper signal level needs to be applied to the base of the transistor for it to turn ON. So the output signal from the OPAMP with a 0.7 V drop(The forward voltage drop across the diode in the transistor) forward biases the LED and turns it ON.
does it really works ?
I love u man thanks bro ♥
Can you please reply
It is not functioning

I like your video. It's very nice to see a young man building all the neat circuits and clearly demonstrating how to do so.
Broo Your Demonstration is Really Clear..
That's the reason why breadboards are best for Learning.
Great
that was really good guide bro thanks! This will really help with my project
Guys u should try this step by step ...Its working..u can trust this guy 😉😊
This project works like a charm..do it when he's doing it..it'll definitely work!! Got full marks today because of it
Dude did u do the same thing as the video did
I mean have u arranged the same componets which was shown in the video
@laxmanA I did exactly same as the video with the components he mentioned
@@lakshmananarvind ok.. Bro
@@lakshmananarvind Bro Which IC should I use for this project?
Ur circuit design is awesome for detecting mobile phones whenever calling is receiving and outgoing.It is possible to design a circuit for detecting electronic gadgets like smartphones, laptop, scanner, printer and desktop computer within the room, without receiving calls and SMS.
Thanks a lot for this video. I tried making this circuit as shown in the video. But when i take a call, the LED only lights up once and turns off and doesnt keep on blinking like shown in the video. Do you have any solutions for this?
The key to the entire circuit is the 22uF capacitor- You need 18mm length on the leads, and the 8mm width of the cap itself to form (essentially) a loop antenna that can detect GHz signals. If it's not working for you, try making sure you keep the length of the 22uF cap leads the proper length.
Can u elaborate?
could i use 0.22 micro polarized capacitor rather than the one that you had shown for 0.22 micro capacitor ?
Thanx working now 👍
@@syedazim6479 Do you need a antena? and can it detect 4g or 5g signal?
@@takbirkhan9154 can you please help me
Great video! but I would like to ask you one thing. From where you get these component s.
Just Amazon
Hello your project is working very well???
THANKS, VERY CLEAR & PERSUASIVE
Great efforts......
hey i liked this project but i need to know which component of this ckt is detecting the phone signal?
Just a small doubt, will this circuit work for 4G/3G signal or will it detect for only 2G signals ? A reply back would be highly appreciated , thank you 😊😊
It is not detecting
plz provide the detailed working of this circuit and the schematic too asap
I also have made a shadow detector circuit. You can also watch it. th-cam.com/video/f1Seudbs5F8/w-d-xo.html
Can you please explain how does the circuit get to know if there is a signal being sent when there is no input channel(antinna etc.)
Does the circuit senses the IR signals at the time of calling and start glowing??? Is it correct??
I liked your video very much. "Thank You", thank you very much. Can you send me the URL for the schematic of the project?Let me know...

Solution for constant LED glowing:
make sure to use the wires minimum and even if you guys do, make sure to keep it small in length.. i performed it through that where i was getting 4G signals detection when i used to bring my phone over the capacitor (0.22 MF), i was told by my professor that it is detecting 4G signals only due to the Capacitor value (0.22MF) being high, while it can detect 3G signals by decreasing the capacitance value of the capacitor (0.22 MF). correct me if i am wrong, if i got anything wrong. thank you:)
Bro is it working please reply bro
bro could you please help me
After using minimal wires still we get continues glow of led
hey bro if it worked for you please reply
@@mrigendrabist2148 @anudeepthodupunoori7115 Yeah, it did.. I worked on the project, a year ago, I avoided using wires mostly. Try out all videos available on TH-cam, if you are not getting any results. Also, there would be schematics available on some websites which may help also.
But most importantly, it didn't work with me on the phone signals, but it used to detect the internet mobile data signals
I tried to do it with ca3140 but it didn’t work the led illuminate all the time can I fix it ti work with ca3140 or I have to get ca3130?
is it okay if we use TIP122 transistor and also can you explain how it works
EXCELLENT VIDEO!!!!
Due to this video only I was able to submit my mobile detector project.
WORKED CORRECTLY...
how to increase the radius of the detector?
@@ivananoos2574 I don't know. I google it a lot but can't find any satisfactory answer.
Hi Mansoor R
Will you plz tell me that by keeping a mobile at some distance from the circuit will it work r not plz
@@shaikneelufarjana1872 It was working when distance between mobile and detector was upto 30cm.
@@Mr19242 Tq but if we place a detector in one place n mobile in some other place what should have to do in the circuit connection do u know abt it
Sir give the brief description of this prohect
@ Gaurav Yash Jain - AYJ please can you further explain the combination of making the LED blinking whilst you make a call or a message
hi gaurav,I want to insert a buzzer with the led in the circuit so
I have to connect the buzzer in the same way the led is connected?
Can we use it for any types of smart phone I mean 4g like ...plz tell me
Prem Pal yes
Yea
i have seen most comments and a major problem is LED keeps on glowing when connected to battery and i also faced the same problem. what is the solution for it? plz reply the answer...
After 5 minutes the turn off,it because discharge of capacitor after some time..after the turn off ,the circuit works
gowtham chowdary bhai meri bhi same problem hai led glow horaha hai to me kya karu
gowtham chowdary plz Bata bhai mere mini project hai
How does that work? Isn't there supposed to be antenna to detect the GSM signals?
Thanks for your way of explanation without wasting time. Hattsoff ☺️😌
Guy you are doing good...but it would be great if you make videos on how these works
Its a fake video
A good mini project but what should be the minimum range of distance of the phone
Same doubt
Me to the same doubt
?
what happens if we use a 1.8M OHM RESISTORS Instead of 2.2M ohm resistors? Will the circuit works and LED glows or is it a minimum requirement that it should be 2.2M OHM RESISTOR
Is there any replacement for CA3130 IC? answer it ASAP thanks
can i use electrolytic capacitor instead of ceramic capacitor for 0.22micro farad
Lakshmi Kruthiga capacitors do "one" thing, store an electric charge. As like my as the capacitance is the sand it should be fine
It is working we can use electrolytic capacitor
Hey plz tell more on what's happening inside the ic and what's the principle on how this works ànd why we use these values of resistors and cpacitors
This actually works quite amazing how simple it is compared to other project that dont work.
My LED is glowing continuously
Can you suggest to me how to resolve it
Sir we do not require antenna for transmission if the mobile is away from the bread board?
How do i increase the range of the mobile phone dectector
cole sydney please tell me..how to increase detector range?
cole sydney watch this th-cam.com/video/35MgFZj1bAE/w-d-xo.html
Hi this looks very good, But I cant see how this can work. Could you please explain for me and others. Many thanks... John :)
till how much range does it detect?please provide the complete report on this project to make the mini project on this
Great tutorial Thanks :)
But this circuit has no range, i mean if you move a meter away it wont work but if you use inductor instead of capacitor it will have a decent range
Faizan ul Haq can you explain in details..
can u plz expilain how i can use inductor instead of capacitor..?that would be a great help
No u can't use inductors instead of capacitor tor these both electronic components work on completely different principal
And it's an opamp circuit it needs capacitor in that block
@@rishikeshs6398
How are you my dear friend
I have a problem I hope you will help me
The circuit only detects the 2g-enabled device
Do not discover an iPhone or a Galaxy device, only Nokia 105
Yes, it will still work if the phone is in silent mode .
but it doesn't wrk when our cell is lost

+Roy Kareh Well I'm certainly not going to help if you keep shouting.
is it possible to use the same circuit as passage detector ??
Any other alternative for 47pm and 0.22uf capacitors
How can we increase its detection range
You can use antenna or increase the antenna height ...
@@ElectrogeekZ antina kha lgayenge
@@punitakushawaha7777 You should connect the antenna with frequency detecting component in your circuit. So that range of frequency detection of mobile frequency detector circuit will increase.

I m facing a problem in its
actually this circuit not detect the mobile phone
can u please help me about this problem
Sachin Mishra Make sure the connections are proper, Pinouts of transistor is okay and nothing is shorted
Ok ok thank you very much
hello. can i use CA3130 s or CA3130 e? really need ur help. thank youu
maximum distance b/w sensor n phone could be?
Anyone know how does it work?
It works as expected. Thanks. However, you should also make a video explaining various parts, functionalities and logic behind this circuit. It would really help the electronic hobbyists.
Bhai kaise kam kr rha hai
Mai banaya hu kam nhi kr rha
Yaaa
Same for us.....can you say any mistakes that we can make here
Same for me it's not working any help
bro could you please help me
do you have a flowchart and block diagram for this?
Will the led bilnk when we r using the browsing on the mobile ??
can u plzzz tell the working of this circuit
ya I want working too
a high speed high current differential amplifier with a light on the output that amplifies electrostatic background noise around a level different than cero (light shines always but flickers more o less when theres 'phonewaves' around) the antenna is unnecesary and would go in the pin 3 in series
the 0.22uF capacitor works as antenna for the circuit. when a incoming/outgoing calls hits the phone the RF is catch by the antenna and after some filtering signal passes through the difference op amp here it amplify and passes to the base of bjt which act here as switch and when it hit the base of bjt transistor turns on and led blinks .
Due to fluctuation in Input signal and Unidirectional operating of LED , LED blinks. (Edit: many types of faults present in this circuit, may not working Properly)
the pnp base is the antena,acts as a dam or a street traffic light in red where a potential or volt is developed and exists loger as electric field in the capacitor
faults? as in?
Also, doesnt it detect mobile internet or wifi?
Hello sir
Can you make more complicated for example adding a beeb sound or anything else
Thank you
Hi ! Enjoy your video very much! However, my led on without sensing a phone . Feel free to help
I want ask a question I have. a LCDTV when any mobile ring or incoming call. then TV started blinging and ring how it is work plz tell urgent
if the mobile is 1km apart also does it detects
Deepthi Muthulakshmi No
only for1.5 m
Badr Hsaini what changes do I make if I need 10metre range?
need to add atenna
Deepthi Muthulakshmi If we attach antenna to the collector of the transistor the range will increase
Shit man !
Damn it!
Led keeps glowing
How?????
can you make a circuit to stop this signal that checks the phone ,basically go unchecked when phone is on
Does the BC548 transistor work as a switch which is off in absence of a wireless and on in presence of a wireless signal ?
And what is the importance of the CA3130 op amp ?
The OpAmp is used as a current to (amplified) voltage converter, the capacitor connected to the inverting and non-inverting terminals of the opamp picks up the signal and provides a small current to the amplifier unbalancing it and then the IC converts the change in terms of voltage... it then turns on the transistor which then lights the LED.
the circuit doesn't work man
Thank you very much Mr Jain.
I would like to know, this circuit is operational within how much distance from the mobile phone?
we have use bc547 transistor but its not working so do we have to use bc548 transistor necessiry ?
kindly need ur help bro its my dld project and every connection is working fine just i am facing transistor problem i think ? looking for ur positive answer ?
How can we use buzzer in this model.... I mean where we should connect the buzzer... I want when the led is glow it shuld also make noice(buzzer)....so will u please tell the circuit using buzzer
How can I order those components together?? Do we need to order everything seperately??
sir ca3130 mrkt me avlbl ni h iski jagah pe koi dusra use kr skte hai??
Thank you Gaurav ..your Video is very helpful, keep sharing.
Nice information but if I wanna replace LED with LCD or 2 LEDs 1 for Incomings and other of outgoings..
Is there any need to connect the phone to circuit....and our IC is burning I don't know why...but as we connect battery it burns out
Would a WIFI signal trigger the sensor as well?
very clear video..nicely explained
What about it's range?
If we want connect in class rooms to find whether the students are using mobiles or not do we have to do any modifications?
hey! I'm planning to make this as a project in the near future. if anyone here has got success in this project, pls tell what is it that makes the led glow?
This is just a rf sensor right??? It cant sense the presence of a phone, only when it is communicating can it sense...nice video...Can you use a JRC4558 dual OP AMP in this circuit.
Is not rf sensor
what apliances that uses CA3130 and 2.2M resistor?
Sir, what made the circuit to detect the signal, when it hasn't any detection device?? Can we make the same circuit using microcontroller, if yes, what would be the required changeS??
Sir ,can we use software for this hardware circuit and do any project?
What is the sensor component used in this circuit
Does it cover long distance between the circuit and the phone
can we use resistor other than 2.2m ohm resistor?
which components can be used in place of 47pF n 2.2M???
can we use an antenna and where to connect it
if i simulate this circuit where'll from i take output???
is it from led or others ???
Working perfectly. Thank you
We did that video on PCB.But that LED is continuously on... What might be the reason??
the project really worked awesome because of u guys i got first place in our open house u guys rock but i xplained them how mch i understood of the circuit but i really wanna noe which recieves the frequency of the phone
hey can u plz help me in my project?? its LED is lightened whn the battery is connected.!!!!! plzzzzzzzzzzzzzzzzzzzzzzzzzzzz plzzzzzzzzz help!
Can we use in smart phone in any types please tell me the answer and we want more examples in that
When I connect battery thd led is blinking but it is not blinking on when the mobile is receiving or outgoing signals
How could u connect the phone to that board ( and there is no connection ) how the led is blowing
I wanted to ask that is there any software which should be installed on the phone or it just gets directly connected to it?
No special software needed
Sir, BC578 ky jagah main BC547 transistor use kr skte hain .
