Psensor Released, The Best Way to Display System Temperatures in Unity

Psensor has been released and is now available in its unstable repository. Psensor is a graphical temperature monitoring tool for Linux. Psensor has already been added to Ubuntu 11.10 archives so it will be available to download from software center in Oneiric.

Psensor Features
  • Displays temperatures of motherboard and CPU sensors (using lm-sensors)
  • Displays temperatures of NVidia GPUs (using XNVCtrl)
  • Displays temperatures of Hard Disk Drives (using hddtemp)
  • Displays rotation speed of fans (using lm-sensors)
  • Also notifies you when temperatures cross a particular pre-defined limit
Today's update brings many new features and tighter integration with Unity without cluttering the top panel with too much info.
  • Shows new globalmenu on Unity panel
  • New sensor preferences window
  • Unity Launcher icon for Pesensor can display the greatest temperature
  • Application Indicator menu contains the information of all sensors for quick access
  • Gtk3 support (Gtk2 still supported)
  • Main window can be closed and shown again using the Application Indicator


First install lm-sensors by running following commands:

sudo apt-get install lm-sensors

Now, run the command sudo sensors-detect to identify your hardware sensors. Confirm that its working by running command sensors from terminal.
