Thanks for the links, Dan. Looks like a build-your-own solution, but I
was hoping for something a bit more turn-key. Jun Ma recommended (via
private e-mail) the HWg-STE, which appears to be a small, network-
attached box that accepts 1-wire probes. He included links to their
international web site (hw-group.com), as well as the Canadian
distributor (hw-group.ca), but no prices are listed. I've e-mailed the
Canadian site, and will see what the price is.
Brad Vokey's brother, Gord, recommended the TemPageR 3E, from
AVTech.com, which I had also already come across. but their US $195
package includes a temperature-only probe. To get humidity as well, I'd
be looking at more than the US $199 for the MicroGoose from ITWatchDogs.com.
Other options I've found include the Newport (newportus.com) iTHX and
iTHX-SD, and the NetworkTechInc.com EnviroMUX-Mini, but they're more
expensive as well. Someone I know at U of Calgary recommended a cheap
solution that came out of there called Phidgets (phidgets.com), but it's
also a build-it-yourself type of solution, which would also require some
programming. (More effort than I want to put into it now, or that I can
justify doing on work time.)
I'm thinking I'll order one MicroGoose from ITWatchDogs.com, and try it
out. If it doesn't do what we want, I can try other options later, and
we've only lost a couple hundred dollars.
Thanks to all who replied or offered suggestions at the meeting.
