Good, but expensive
Posted by Gareth Halfacree on 26th Sep 2011
The RHT03 (the actual product supplied, which is identical to the DHT22) is quick, accurate, and works on a single wire - but it's also pretty expensive.
There's a full review - plus a link to an Arduino library for communicating with it - over here:
