Hardware Monitor Widget Edition is the Dashboard version of its "bigger brother"
Hardware Monitor. You need a working registered copy of Hardware Monitor in order to fully use this widget. The applications are designed to give you access to all sensor readings Mac OS X uses to monitor and cool your computer. The widget allows you to select two of your computer's sensors which should be displayed via Dashboard.
Unlike other widgets, Hardware Monitor is capable of processing the hardware calibration data Apple stores individually into each G5-based computer. So it displays the exact readings Mac OS X internally uses for cooling control, not just an "educated guess".
New in this version:
On PowerPC hardware, support for S.M.A.R.T. hard drive sensors accessed via SATA interfaces has been enhanced. The widget will now accept the temperature sensors of unknown SATA drive models. (This has always been the standard on Intel-based computers.)
The support for hard drive sensors controlled via proprietary drivers of Sonnet and FirmTek has been enhanced.
The default number of displayed digits behind the decimal point is now automatically set to zero in cases where it is known that the sensor hardware does not provide more significant digits.
Corrected a problem where the temperature values displayed for the cores of the Intel P7350 processor have been shifted by 15 degrees Celsius.

Limitations: The program will only display readouts of temperature sensors, not other values like voltage, current, fan speed, etc.
