CPU temperature monitoring

So far I have entered „sensors“ into the terminal from time to time.
Now I found out that pmcputemp is already included in Fatdog.
It doesn´t appear in the tray automatically.
I can launch it only via terminal (I created a simple script in /root/startup with text: <urxvt -e & pmcputemp> and it works).
The temperature values displayed simultaneously by pmcputemp in the tray and the „sensors“ in terminal seem to be different.
Which one is closer to reality?

I don't use pmcputemp, because there's already:
Right-click the LxQt-panel -> Manage Widgets -> + -> Sensors
It supports multiple sensor readings, through libsensors, just like the sensors command.
Greetings!

@JakeSFR ,
I didn't know about this.
Very nice 
! Thank you.
I also don't use pmcputemp from today 
.

This is a extract of the code I use to show a temperature icon in the tray of my bespoke containers. Generates its own .svg icon. Updates every 5 seconds (sleep 5 in _temp() function)
Code: Select all
#!/bin/bash
# Requires 'sit' to have been installed (from gslapt/repo) as that is used
# to stuff the temperature icon into the tray
REDTHRESHOLD=66 # CPU temperature at which icon colour turns red
_tempsvg() { # cpu temperature .svg
cat <<EOF >/tmp/.temperature.svg
