Hardware Sensors Indicator

Hardware Sensors Indicator provides temperature, fan and voltage sensor

readings within the panel of your desktop.

When running GNOME Shell a shell extension is required to view

sensors readings within the top panel. Therefore it is recommended to

also install either the KStatusNotifierItem/AppIndicator Support

extension

https://extensions.gnome.org/extension/615/appindicator-support/, or

the Hardware Sensors Indicator extension

https://extensions.gnome.org/extension/336/hardware-sensors-indicator/

so that sensor readings are visible.
