Nice product, awkward packaging

I would probably order the cased one next time as I didn't realise this is really meant to be PCB mounted... otherwise performs as specified and does the job!

Easy to use and accurate

More stable than a TMP36 and with added humidity. I found the TMP36 had to be averaged out but this sensor is steady.
A great little sensor for those starting out Arduino or Raspberry Pi. Either upload the data or put on an LCD display.
A little pricey bu

Good, but expensive
Monday, 26 September 2011  |  Gareth

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:
