A question for those knowledgeable in this area... if I was looking to measure humidity in a residential setting, what would be the best type of sensor to use? I've done basic reading on the various types, but I'd like to hear opinions from folks who really know this topic and what's out there, practical application, etc.
Ideally, this sensor would identify undesirably high humidity conditions in a normal household environment, would probably be replaced rather than recalibrated once installed, and would be sufficiently accurate to prevent any serious likelihood of false positives.
Cost, size, and reliability are of particular interest.
Anyone have any thoughts on this topic? I would greatly appreciate any input. If this would be better posted in a different newsgroup, please let me know.
