Magnetic sensor largest range

Hello, which magnetic sensor has the largest range?

Model : distance

TLE 4905L : 10mm

What's your budget?
What do you mean magnetic sensor?
Do you have any size constraints?
What is your project?
Are you a spambot?
You really don't need to know which is the largest range because it's probably something used by NASA.

On Earth, you are limited by the Earth's magnetic field.

A magnetometer, or compass chip can detect automobiles several meters away.

To answer that literary it is a Fluxgate magnetometer

As for models this place has some to chose from:- http://www.bartington.com/catalogs/three-axis-fluxgate-magnetometers

You can only determine the range once you know what magnetic field strength you are trying to detect.

I'm looking for a sensor that counts up to 5 cm

INTP:

  1. What's your budget?
  2. What do you mean magnetic sensor?
  3. Do you have any size constraints?
  4. What is your project?
  5. Are you a spambot?

  1. I'm not sure about the budget.
  2. https://www.youtube.com/watch?v=sMl4xTSJC5U similar to the clip, but the magnet is at a greater distance.
    3.the dimensions are up to 95 x 18 mm.
  3. my project is very specific and require magnetic sensors to take into account every passing of them.
  4. I'm not a spambot! I'm human :slight_smile:
  1. Impossible to help you further.
  2. I am not going to watch someone else's video. Just tell us what you are trying to do.
  3. Ok.
  4. You have very specific "thems"? I have a very specific answer: Those.
  5. Thankyou.

For larger distance I used 30 000 turns coil - distance 14m for 3.5" speaker magnet

I want to put two magnets at certain intervals on a horizontal. Once the magnetic sensor first reads magnet 1 and then magnet 2 (the direction is forward), it stops performing the number of times it has been assigned by the buttons. When you first read magnet 2, then magnet 1 (the direction is back).

That makes even less sense.

"Stops performing" You never told us what was started.

"The buttons" What buttons?

It almost seems like you want to identify the magnets. Like the sensor can see some identifying marks on the magnets. Magnets only have N and S. There is no way to identify a permanent magnet from its magnetism.

And without knowing the strength of these magnets you can not estimate the distance over which they can be detected with any one sensor.

Instead moving the sensor move the magnet, you need two sensors and one magnet.

Here is your sensor.
