gnome-shell-extension-sensors

gnome-shell-extension-sensors (previously known as gnome-shell-extension-cpu-temperature) is an extension for displaying CPU temperature, hard disk temperature, voltage and CPU fan RPM in GNOME Shell.

The extension uses sensors from lm_sensors package (lm-sensors for Debian systems) to read temperature for different CPU cores and adapters, voltage data and fan speed.

Optionally, this extension uses the UDisks2 dbus interface or hddtemp as fallback to read hard drive temperature data.
