mate-sensors-applet binary package in Ubuntu Focal amd64

 MATE Sensors Applet is an applet for the MATE panel that displays
 readings from hardware sensors, including temperatures, fan speeds and
 voltage readings.
 .
 It can gather data from the following sources:
  * ACPI thermal zones, via the Linux kernel ACPI modules
  * Linux kernel i2c modules
  * lm-sensors (libsensors)
  * Linux kernel i8k module (for Dell Inspiron Laptops)
  * Linux kernel ibm-acpi module
  * Linux kernel PowerPC modules therm_adt746x and therm_windtunnel
  * Linux kernel iMac G5 Windfarm module
  * hddtemp daemon for reading temperatures from S.M.A.R.T. equipped hard disks
  * Linux kernel Omnibook module
  * NVIDIA graphics cards (supplied with mate-sensors-applet-nvidia package)
  * Linux kernel sonypi module (for Sony Vaio laptops)
 .
 Alarms can be set for each sensor to notify the user once a certain high or
 low value has been reached, and can be configured to execute a given command
 at given repeated intervals.
