Baby Temperature Monitor

["lawrert" <lawrert@xxxxxxxxx>]

Please would someone be able to offer help ? Apologies if seems a
little off topic.

I would like to set up a temperature monitor (too hot and too cold).
I have a Comfort Alarm and could use a PC based system.  I worry that
I need to guarantee the system will always work so needs to be more
off the shelf system (than a home made product).  I would like an
audible alarm.

thanks richard
