How to use STEVAL-MKI208V1K to collect vibration data of bearings?

If I use STEVAL-MKI208V1K to collect vibration data of bearings, do I just need to fix this board on the bearing where I want to take data?
Thanks

I take lots of accelerometer measurements in lots of different places,  if there is a chance of differential movement from the bearing I would stick it down.  A picture or sketch would help.  

Some of our people fix and some don't.

STEVAL-MKI208V1K is just a bare board - so not suitable for permanent mounting, and/or use in an unprotected environment!

Obviously, it will need to be mechanically attached so that the vibration of the bearing will be "felt" by  the sensor!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

You can create a small box for it.  I have several in museum. 

It will stick inside an electrical box on a bridge in Iowa with the right tape, and then record through really cold weather.  

If it is a large bearing and the device is sitting flat, it will work in a quiet environment.  

They are actually more robust than they look, until the rubber band that you use to stick somethings together breaks.  

That happened with Flint mounted on the gunboat Philadelphia in the Smithsonian Museum, reliable as heck for years and then dead.  PI finally said, rubber band broken.  I suggested a simple fix, a new rubber band. 

All our accelerometers have names, much better than numbers.

True, most of the time.

Hello,
If I add a copper column to the evaluation board as shown in Figure 1 and connect the copper column to a magnet, and the magnet is attached to the red box on the test bench in Figure 2, can this operation collect vibration data normally?
Thank you for your reply.
