    A mobile detector which will detect mobile phones or have i misunderstood your question.

    yes you are right a mobile detector which will detect when the mobile is being used to call or recieve call or send or receive sms to avoid disturbance in public places like hospitals,offices, labs, temples,etc...
    if you have any circuit for that then plz send it to me

    I have no circuit but from my knowledge of telecomms i presume that you should build a circuit to detect the uplink frequencies of the mobile system architecture in question. You do know the frequencies if you don't you can google them.

    Well I don't know how to do it but well, mobile phones have electro-magnetic flux flowing around them when they are receiving/making a call or sms, if you just wind a small coil and amplify the signal and attach it to an LED, whenever you will take that LED system near the phone in about a range 1 or 2 feet max, the LED will glow up. You might use the electricity produced to make audio signals also, but well havnt thought much on that. :\

    Have you also noted that when you are getting a call and you are near a radio there is interference on the transmission. Maybe you could use this to your advantage, say build an ultra sensitive radio.

    yeah that's the radio frequencies creating disturbances but these only work when the phone is making/receiving a call or sms, and the project should be able to catch the phone in non-operating condition only. 😕

    I found a device on the market, but it's not a detector. If you use that device, it will shield your cell phone signal, you will not receive a call or call a number out.

    i guess for that you dont need to have any circuit..simply you put your cell in a metal box, the EM signals cannot penetrate through metal

    hi friends, which filter is used in cell after recieving the signals.. ie resistors, capacitors are not work as proper in Ghz frequency range then which is used for it
