  2. 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:
