A Graphical Temperature Monitor

Psensor is a graphical hardware temperature monitor for Linux.

It can monitor:

  • the temperature of the motherboard and CPU sensors (using lm-sensors).
  • the temperature of the NVidia GPUs (using XNVCtrl).
  • the temperature of ATI/AMD GPUs (not enabled in Ubuntu PPAs or official distribution repositories, see the instructions for enabling its support).
  • the temperature of the Hard Disk Drives (using hddtemp or libatasmart).
  • the rotation speed of the fans (using lm-sensors).
  • the CPU usage (since and using Gtop2).

The application is designed to be simple and easy to use. The CPU and memory consumption are not significant.

The last stable version is 1.0.2.

The last development version is 1.0.2.

Psensor is released under GPLv2 license terms.

Usage Information

First step is to install lm-sensors, for Ubuntu:

sudo apt-get install lm-sensors

Then, starts the detection of your hardware sensors:

sudo sensors-detect

Verify that it works:


It should display something like:

Adapter: ISA adapter
Core 0:      +46.0C  (high = +76.0C, crit = +100.0C)

Adapter: ISA adapter
Core 1:      +44.0C  (high = +76.0C, crit = +100.0C)


Then you can proceed to the installation of psensor. For Ubuntu and derivatives, you should look at the Ubuntu support page.

And finally launch psensor executable.

More information are available in the Psensor FAQ.

Linux Distribution Support

Psensor should compile on any modern distribution including GTK+ v3 and lm-sensors which are quite common. For Linux Distribution still stuck on GTK+ v2, the old 0.6.x releases of Psensor can be used.

If you have trouble compiling Psensor on a specific Linux distribution, don’t hesitate to report it.

Binary packages of Psensor are available for few Linux distributions:
