Compass sensor suggestion

Other Hardware Sensors
1

I'm looking to a compass chip or board. Can you suggest me something?
The requirements for the compass in my project are:

  • There's an ironic structure under the compass board/chip, so it must be tolerate it.
  • Resolution can be around 1 degrees but not more than that.

look for "compass with Hard & soft iron magnetic compensation" from your usual seller

you'll find commercial grade 2D digital compass. they don't come very cheap though

may be you can find an (obsolete)

there are others like

Hi, @werktx
Welcome to the forum.

What is the application?

Thanks.. Tom.. :smiley: :+1: :coffee: :australia:

Hello @TomGeorge

My application is a hobby project. It's going to be a speedometer for bicycle and utilizes GPS to estimate the speed. I also want to find the north angle and display it on the screen of the gadget. Although I can estimate the border of movement and calculate the approx. value of north angle, I still am looking for to see if I can find an actual compass to make it more accurate.

The chassis of the housing I have considered for it is made of iron (found it in my scrap parts).

Hi Jackson, thanks for suggestion, but those pars are overkill for a hobby project I guess :slight_smile:

you can try your luck with any IMU then and try to see if you can compensate for the ironic structure influence through an initial calibration.

And maybe the sensor should be as close to the center of the iron chassis as possible. Thus, magnetic field distortion is minimal (or self compensated).
