We've published a paper about these in Sensors [ http://www.mdpi.com/1424-8220/18/2/530  } (open access, free pdf download) describing how we use these in caves and underwater, but we also use them on the surface in weather stations for atmospheric conditions, etc. These are stand alone loggers, and are relatively simple devices compared to the Pi-based wireless FIDO's that people have already been talking about in the FarmHack forums. So no text messages, etc.

I recently ran across the temperature logger tutorial posted a while ago by jennajane, and wanted to chime in. First of all way to go! I started my path to learning Arduinos with the same Adafruit logger shield not very long ago, and it's been an entertaining hobby for me ever since. But I have been plugging away at it for a while now, and I just posted a DIY plan for a very inexpensive ($10-15) logger based on the sparkfun Pro Mini boards. Also there is a waterproof housing I made from PVC pipe with only one hack-saw cut & some PVC adhesive for about $10.
