temperature acquisition on FreeBSD

[Patrick Proniewski]

Hello,

(I'm not sure if it's the right ML for this question, if not, please 
disregard this post)

I would like to plug on my freebsd box (router/firewall/small http 
server) a handle of temperature acquisition probe, but I can't even 
find the proper hardware.
I would like something to plug on the serial port (or USB port) that 
allows me to record temperature with up to 5 probes (at least 2 probes, 
but 5 or more would be great).
In terms of software, I've absolutely no idea how it's supposed to 
work, but something that feed data into a database would be great 
(rrdtool, mysql, whatever...)

any hint greatly appreciated
