lm_sensors

[Steven Pritchard <steve@silug.org>]

I've been meaning to mention this for a while...  There's a kernel
module called lm_sensors (http://www.netroedge.com/~lm78/) that gives
you access to the hardware sensors on newer motherboards.  For
example, with an older version of lm_sensors (1.4.12), /proc/sensors
looks like this:

Vcore:	+3.20V	(min = +3.05V,	max = +3.74V)	
Vcore2:	+3.20V	(min = +3.05V,	max = +3.74V)	
+3.3V:	+3.55V	(min = +2.97V,	max = +3.63V)	
+5V:	+5.13V	(min = +4.48V,	max = +5.48V)	
+12V:	+12.22V	(min = +10.82V,	max = +13.19V)	
-12V:	-11.62V	(min = -10.79V,	max = -13.18V)	
-5V:	-4.96V	(min = -4.50V,	max = -5.49V)	
Fan1:	0 rpm   	(min=3000 rpm)   	ALARM	(not connected?)
Fan2:	0 rpm   	(min=3000 rpm)   	ALARM	(not connected?)
Fan3:	0 rpm   	(min=3000 rpm)   	ALARM	(not connected?)
Mainboard: 29 C	(min = 0 C,	max = 50 C)	
Other alarms: (none)
VID:	 3.40	
Temp-1:	+34.5 C	(Tos = +50.0 C,	Thyst = +45.0 C)

It works quite well on my ASUS TX-97.  YMMV.

Anyway, O'Reilly just sent me a review copy of Learning Perl/Tk for
the Perl group (http://springfield.pm.org/ - get on the mailing
list!).  I decided to write something that would display my CPU and
mainboard temperature.  Take a look at
http://www.silug.org/~steve/software/scripts/perl/tempmontk for what I
came up with.  If you run it with "tempmontk -- -small", it works well
swallowed in the KDE panel.
