ALL THESE CONFIGURATIONS ARE BAD, THERE IS ONE IR SYSTEM WORK

hello kaveh

I was using bpw 41 n before and it did not give the exact location. But it received the full signal from 10 meters. Which RX do you use?

It must work.

Hi
Have you placed your Rx led in a small tube for increasing directivity?

No. I didn't do that. can you tell me how to do it? or illustrated explanation.

I have personally cut a piece of a plastic tube taken from a pen! Led can be fit inside there beautifully. Use a piece of about 2 cm and paint it black. I have opened a hole at the front side of the box and i glued this plastic tube at the internal space of the box. This is for to protect the tube from knocking when you use it. Fix the IR led at the bottom of the tube, and now the light needs to go in a straight line for to reach the sensor.

Yes. It's very logical. There is no space on my old device. I should make a new one.
The old one found the piece shown in the picture last. It makes more sense to make a new one.


thanks

What circuit you use? Can you post it?

It's not a very special circuit, it's simple 555 and IR RX.
Precision belongs to your mastery skill. The secret is not in these circuits. It can detect any circuit no matter underground.
