Written by Fabian Nowak, this is a hardware sensors plugin for the panel. For now, it only works on Linux and requires libsensors to display your mainboard sensors and fan speeds. Furthermore, it supports hddtemp to surveil your hard disk's temperature values. Source code and Debian packages are available.
Add the plugin to the panel and start checking some checkboxes in the sensors table.
You can specify the color you want the text to appear, rename the sensor so that the tooltip displays the new name.
You can also display your values graphically, meaning they are displayed by bars. For those bars, you can specify min and max values which result in red colored bars, when those min or max values are reached.
If you don't like the green bars, you can check to display colored bars, thus using the color values specified for each sensor.

Additionally to the 4.2 or 4.4 panel (and its headers if you want to build it on your own), you need libsensors3 (and its headers…) for up to version 0.10.0. Versions newer than that one will detect the available libraries at configure-time and compile only with those found on your system.
Install ``hddtemp´´ to be able to monitor your harddrives as well.
