I have created a Qt-based app to display and evaluate your computers sensor data using lm-sensors as backend. It's a modern approach using Qt Quick and QML in combination with OpenGL to render high quality graphs. I did it as a proof-of-concept but like to share it anyway.
How to install
for Ubuntu 13.10:
sudo add-apt-repository ppa:henrythasler/pwnsensor sudo apt-get update apt-get install pwnsensor
pwnsensor can then be found under the system menu.
Sourcecode and additional information is available on github
