Re: [hobbit] Temperature Graphs

If the systems don't already have their own internal heat sensors, you can
easily add a One-Wire sensor to the closet.  You can get ready-built modules
here:

and either the serial or the USB adaptor:

Software to read One-Wire devices is here:

   http://www.digitemp.com/software.shtml

You'll also need their cable to connect the module to the adaptor.  If
you're handy with a soldering iron you could skip the module and just get
the bare temperature sensor (DS18S20), cut one jack off a phone cord and
solder the sensor to the relevant wires.  The other jack on the phone wire
will plug directly into the adaptor.

I've got a script for reading the temps via digitemp and reporting to Xymon,
but the machine it's on is currently unreachable.

I'm not affiliated in any way to Hobby Boards, not even as a customer, but I
do have some of those sensors monitoring temps in parts of my workshop.
