Product review (5 stars): #$@#** Arduino!!!
This sensor is theoretically awesome but I'm stuck in the cesspool of never-been-able-to-get-an-arduino-sketch-working hell.  To be fair, I did get this up and running for a few hours in a test sketch and it worked fine.  I was prepared for the slow polling time but was actually rather surprised to see that there were 0 decimal points in accuracy in temperature (in C).  Didn't verify my temps with other instruments but measuring air temperature and humidity in my house it passed the smell test easily.

The breakout board is really what you're paying for in this product and with that I had no issue.  Now if I could just get a miracle to help me out on my next arduino project.
