Mike, I got a bit busy at work or else I would have responded sooner. (Yeah, I know. Strange idea to actually do some work while at work.)
Anyways, I'm doing something like this for our lab at work. Unfortunately, I probably can't share my Perl code (employer's intellectual property rights situation), but I'll try to share the concept and whatever else I can without getting into trouble with my employer. The device that I used is the Digi Watchport/H sensor since we already are using those for some other work. If you're not interested in the humidity readings, you might find the Watchport/T sensor to be more inline with your needs. The link below is for more details from the manufacturer. http://www.digi.com/products/wirelessdropinnetworking/sensors/din-watchport-sensors.jsp#models In my implementation, I set up 4 of these sensors in each of the A/C zones for our lab. I connected all four of them to a single system running Windows. On that system, I set up a Perl script that connected to the sensors using the Win32::SerialPort and used Net::EasyTCP to set up a "telnet" server. The basic behavior is that when a "client" connects, this script would: 1) Connect to a temperature/humidty sensor 2) Retrieve a reading 3) Sending reading to client 4) Repeat steps 1-3 for remaining sensors and then close the connection I set this script (actually I bundled it into a self contained executable using PerlApp from ActiveState) as a scheduled task to run when the OS comes up. Eventually, I probably should update the script to be run as a service. There may be better and/or cheaper methods of accomplishing the same thing, but that's what I used. Let me know if you have any questions about my implementation. Good luck on getting things set up!
