What people here want to know is how the white sensor is connected the Android device, and what sensor is being used?
To be honest, I'm not even sure what we're seeing in the video. It just looks like a display of random noise.

me too dear Qiaozhi this vido shows nothing. So we know how to work a detector with android

but strange for me this videos. remains to be clarified things or explain a little details how the principle of operation and how are the two connected devices mean the Gun and Android.

why not show something the video; detector is the Gold gun with one CONNECTED androint the amplifier output, the receiver is tuned to 77.5 khz,.

How is it connected to the Android device? Is it hard-wired (USB), or using Bluetooth?

[taxma1981]

With cable,sorry for my English

[okantex]

look at the phone screen
only open states are alarm clock and headphones .
both of them are outputs.
so only input of mobile is speaking microphone, since you plug headphone ,it must be closed.
so ,does this phone has mic on the headphone cable ?
waiting technical advises and vidoe or photos showing the connectins ,please

[taxma1981]

I use a cable from headphones with mic but I only connected the microphone n the ground in this way that I take from the amplifier to see on the screen of the program

[taxma1981]

null signal

Hi Taxma1981,

I had a similar project. but I did not try it on phone before.
today I bought a headphone set with microphone.
I cut the cable .. on jack
1.( tip of jack) is buzzer
2. is buzzer
3. is microphone input
4. is ground

I used 3. and 4. connections . , 3. is microphobe + and 4. is general ground.

let me tell you my tests from begining,

I took headphone set.
I opened microphone part of headphone set. and disconnected buzzers side of small pcb.
then I disconnect phone side's buzzer connections. I left just lines which are connected to 3. and 4. tips of jack.

here the story begins.
I just left microphone input alive.
when I connected jack to mobile , on the screen ,I can see microphone is connected. take care , not only headphones.
there is 2 different symbols , one is just headphone, other is headphone and mic is connected.

in your videos ,only headphone is active.

anyway , lets continue on story.

I was speaking to microphone and watching on the secreen. that is good. only input was the microphone on the tip of the cable .

when I cut these connections and connect them to my experimental pcb.
vola.
there were no symbols left behind.
But , on the otherhand , I was watching the signal from the circuit. , I was recieving the signal even there is no symbol of headphone.

that is also okay,but I discovered something else ,too.
I was also reciveing the noise in the room. while I was speaking ,screen is also changing. so , on mobile microphone of the mobile is still active.

Do you have the same problem?

please try to make noise , sounds while you are watching the signal of your circuit on the screen.

now, I need advices on ,how to close on mobile mic. or what sort of connection is needed to close the on mobile phone.
becasue , at my tests , when there was only the orginal microhone of headphone set was left on the tip of cable , only entrance was microphone on the tip , not the on mobile microphone.

waiting offers.

You get earphones with microphone and cut the microphone will only keep the cord with jack plug opium will link to mobile phone, the other end of the cut cable will connect a simple plug jack, will join the ground and the milrofon only, so the screen of your mobile will only see that you get from the amplifier's gun, the night I will make text

[okantex]

please do the test, because your phone is probably also hearing the noise in the room
speak to onboard microphone of your mobile while your system is connected to your phone.
does your voice effect the screen or not ?

[taxma1981]

not not hear any noise, we see that records the Gold gun, know what's going on with yours, an.to you put directly on the mobile jack recorded and the noise in the house, you should slowly the pressure until I reset the screen with The program, run tests and see
