Electronic Compass

[Guest]

How can i make an electronics compass?

It can consist of a circle of LEDs and the LED facing north will light up.

OR:-

A single LED and moment the device faces north the LED lights up.

You must start by identifing the magnetic compass sensor you will use. Some common sensors are:

KMZ52 from Philips
HM55B from Hitachi
1490 Compass Sensor

Then you can take a look to some schematics/application notes to see how this can be intergrated to your system:

You are not the first in this forum who wants to make a compass. I suggest using a regular mechanic compass - much easier if you only want to look at it.

Hi Siddharth,

I think that would be a very interesting project to take on , although I think it would be difficult to make an electronic compass, that could improve on the simplicity and reliability of a mechanical compass.

I know which one I would choose, if I was heading into the outback .

Good luck, I hope you are planning on posting your progress here 8).

It is just my curiosity.

I just would like to find ideas to make one; how to approach it.

If a particular method is simple cheap then i'll make one

1490 looks good.
