Mark,
Three years ago we installed fifteen
Hobo U12 units (records temperature, relative humidity and light
levels) in exhibit areas scattered about the airport system. I walk
around quarterly with a laptop and a cable to download the contents of
each and re-launch them on site. They have been very easy, reliable
and they are not expensive. The software has been good, too. If
they record the type of information you need to have I recommend them.

Good luck,
