We use an Uptime Devices SH-2, with both temp and humidity monitoring.

It can send email alerts on its own, but I found that if it rode your
selected threshold (i.e., you set the alert at 75 degrees, and room
temp crossing 75 degrees in both directions, repeatedly) it would send
an email each time it crossed the boundary, in each direction - during
one problem period over 200 times over a weekend, all going to my cell
phone...

However, it also implements snmp, and I have effectively turned off
the email alerts, and am polling with Servers Alive, which is a very
inexpensive monitoring program from woodstone.nu. I'd imagine that
Nagios or other good monitoring programs would be able to do the same
thing. This has worked out very well for us.

It's been accurate and reliable, and was inexpensive to purchase, so
was a worthwhile investment for us.
