Hi all,
I need for a project to put a sensor (don't know which yet) which tells me the angle of itself [0-360°].
I cannot use an encoder, or other mechanical part.
I tought to use a compass/magnetometer , is it correct ?
Which sensor can I use ?
Hi,
Can you tell us the application?
Then we can possibly give a suitable answer.
Thanks.. Tom.... 
Just a school project 
Hi,
What angle too?
What will be your reference?
Have you been given any parts to start with?
Thanks.. Tom...
Not started yet, just wondering which sensor I should use.
I will probably define a 0° reference point but don't know yet how to 
Do you have any suggestion ?
Hi,
Has this been given to you as a project, or have you developed this idea yourself?
If it has been given to you, can you post a copy of what the project document states, please?
Thanks.. Tom...
My idea.
Do you have any suggestion ?
If you want a magnetic heading, use a magnetometer (compass). It can be fooled by nearby metal, permanent magnets, or electrical currents.
Outdoors, over tens of meters, a GPS can give you a 'bearing' (the direction of travel) but not a 'heading' (the direction you are pointing) by comparing two recent positions.
Yes, there are many magnetometer modules available for Arduino. They don't work out of the box and need to be calibrated before they work as electronic compasses.

Failed to specify in what plane.
If in the horizontal plane, a magnetometer.
If in the vertical plane, an accelerator will give you half the information.
Perhaps you should explain the purpose.
I thought with the image it was clear, my bad.
Rotation on the Z axis; so the pivot will be in the center of arduino and I need to detect the angle of rotation ( probably I need to define which position correspond to 0° ).
Hope is clear enough
