This is a simple text based temperature display using LCDLabel
Made as an example it is simple and has many descriptive comments.

Gets temperature in one of 3 ways,
 Either runs a command and uses it's direct output or
 loads a temp file that stores the temperature as a simple number being the temperature X 1000

For raspberry pi many other systems simply give it the file path…
'/sys/class/thermal/thermal_zone0/temp'

Auto-detect checks ALL /sys/class/thermal zones and reports the hottest one found.

or it can use a shell command like sensors (from package lm-sensors) with grep and awk to get the temperature text.
Use 'sudo apt-get install lm-sensors' or use your package manager to install.

Command Example…

The above command runs 'sensors', uses grep to find the line with 'Core 0' in it that for me looks like this…
Core 0:       +45.0°C  (high = +82.0°C, crit = +100.0°C)

and then uses awk to get the 3rd bit of text '+45.0°C' (space separation makes 'Core 0:' 2 words)

Written in Gambas basic
Code has FULL comments explaining everything.
Has a minimum-requirement-installer to install required gambas components.

Other features…
Change background / text and highlight colour
Set Time delay between checks.
Show/Hide Window border/titlebar
Drag-Move/resize window

(Note this is version 1.2 , scroll down for updated version 1.4)

updated this to auto-detect temp reading and resize window is possible.

I am looking at the program and I think an option to display what the temperature relates to would be helpful. The display shows 52.0 then 44.0 and that's it. What is 52 or 44?

The program icon is missing.

EDIT: -

I thought this might be fun, so I have made a simple version of this: -

I've updated the program in the first post to have a settings window to select sensor method
also updated the tooltips to show details about the sensor reading (as shown in pic)


hehe yeah a simple version is simple enough but i had to have some features ,
like i had to import and edit the LCDLabel.class just so i could adjust the LCD base colour (the not lit up bits)

This started as a simple example but went a bit past that over time  :roll:

Updates…..

Option to show on 2 screens.   opens another window so you can have one on each screen.

As well as the temp you can set a Date Format string /lang/format - Gambas Documentation and set the font/size/color

optional colour mode , you can set a cold/warm/hot colour and the main lcd colour blends according to temperature. (there is a test slider on the colour settings page)

enable/disable autostart with system on boot

Screenshot shows both screens.

 It works well, nice job. My computer runs a lot hotter than yours, showing at around 60.00°.
