Can force distort accelerometer reading?

Hi

I have been struggling getting a decent angle output out of an accelerometer, as the output is jumpy but also gets a couple of degrees off for angles around 70degrees for some reason.

I do not understand the way accelerometers read acceleration so I was wondering whether applying force to is (eg pushing on it without it actually moving) would count as 'acceleration' which would cause distorsion in the signal, or not. As I have a bunch of wires connected to it, I though this might possibly have something to do with it (even though I would instinctively think no, I'm running out of ideas :~ )

Thanks

No, but you might have intermittent connections.

If properly calibrated, consumer grade, 3 axis accelerometers are accurate to about 1 degree in determining orientation, at best.
