Yeah, i went there, we tried with various oscilloscopes, spectrum analyzers an so on, yet we could not find anything.
So i continued testing out various stuff and eventually i found what the issue is, though i have no idea yet how to solve it.
It seems like the sensor is quite sensitive to the ground connection, and in case i connect the ground of my board to the Earth from a power outlet, or to the ground from an USB Port on a laptop - it works quite fine, once i disconnect it - the fluctuations start.
Now that this is easily reproducible i will ask some experts to give advice specifically on this. I hope there is some electronic know-how bit that i am missing
