My GH is a bit too far from the house for the Radio Shack units to reach,

I bought an Oregon Scientific unit - temperature (with alarms and

by
the atomic clock broadcasts.

Being a geek, I've looked at some of the dallas semiconductor one
wire sensors and have contemplated using one of the standard
microprocessor prototype boards to do data collection and dissimenation
from several such sensors.

Unfortunately, work has me doing way too much overtime destroying
the North American phone system[1], so I don't have time to tinker.

Chris,

When you DO find the time to tinker, you might look at motes (a bleeding
edge technology from Intel, and how you might connect these sensors you
mention to the motes. That would mean that you could have your data
collection and dissemination hardware scattered over several hectares, and
they'd configure themselves into a wireless network. The all you'd need is
a base station to connect to that wireless network and to your desktop
computer. I'd assume that you could also add controllers to the mix so that
you can have fine grained control over the environment your most valuable
plants experience. You can't get motes directly from Intel, although they
have several web pages devoted to it. I believe you have to go through a
company called Crossbow. You might enjoy reading about motes anyway.

Cheers,

Ted
