I'm not disputing the remedy. Just suggesting there may indeed be nothing wrong with the sensor after all.


I don't believe you said how you are powering the Mega - USB or Vin + on-board regulator?  On-board regulator is likely to be much cleaner.

I've been powering the Mega via the USB plug, but yesterday I tried the AC adapter and still got some noise. I didn't do any statistical tests to know whether it made any difference, but it did seem slightly less noisy when using the adapter.
