Yes, I think so - how much do they fluctuate by? Have a look at the chip's datasheet - it should have some numbers.
As soon as you start doing stuff with the real world, absolutely everything you read has a percentage error. Often a device will give you more bits of data than it is actually accurate to - because over time you could do some filtering on those values and you might just squeeze a little more out of it.
Is this normal?
I have been playing with the MPU6050, but I've noticed that the
mpu.getRotation()
values, etc, fluctuate a lot even if the accelerometer is completely still. Is this expected?Maybe the
getRotation()
values represent a small delta, so they fluctuate from vibrations and/or imprecision?I haven't figured out how to normalize the value from the four functions in the doc into yaw/pitch/roll, maybe that will be more stable?
(I'm completely new to this stuff, so I have no idea, yet!)
