Quick google search, the
lm-sensors package should fit your purpose. (Note I'll be summarizing this article).
Open a terminal window.
sudo apt-get install lm-sensors
Let the process finish, then
And answer yes to the corresponding yes or no questions. After this is finished you have a choice to either insert the sensors into /etc/modules automatically (yes) or to manually do it later (no.)
Next, load the necessary modules with
sudo service kmod start
You will need a monitoring program, further down the article's page there are a few listed,
psensor being the first listed. Install (your choice)...
sudo apt-get install psensor
And launch the executable (or run the application from the terminal window). You should now be able to monitor your sensors.
For the tablet sensor (From another AU post):
sudo apt install iio-sensor-proxy inotify-tools
NB: You might have to put your computer to sleep and wake it up for the sensor to work. After that, it keeps working.
