MetaWearR Magnetic Interference
I collected metawearR magnetometer data while rotating the device.
The data is shown in image 1. x and y values are constant. z values are almost constant.
I guess it is interference from other parts of the device.
Therefore i opened the device and adjusted positions of the cylindrical sensor and battery.
shown in image 2.
Then i collect magnetic data again.
The data is shown in image 3. They changed over time.
How can i eliminate the interference?
Is there a similar problem with the latest model? We are going to purchase some MetaMotionR r3. We are worried about this issue now.
Thanks.

That's not a sensor, that's the buzzer you ordered with your board.
Does the stuck magnetic field values consistently happen if the buzzer is near the magnetometer.
Yes. The values are often {x: -0.002048000T, y: -0.002048000T, z: -0.002047938T}.
They are not stuck if the buzzer is not near.
Thanks for the reply.
I've forwarded this post to the hardware engineer. We'll update this post with any new information.
