Using Sparkfun's HIH-4030 Breakout with my Arduino Mega, I'm getting occasional dips and peaks in the sensor's humidity readings. The dips and peaks can be as high as 10% humidity and are brief enough that they're almost certainly noise rather than signal. I've tested the Arduino itself for noise in…
