DIYS DIGITAL THERMOMETER WITH PROBE

[kingofnobbys]

Comparison of typical probes used to measure temperature electronically:

A little bit of electronics : Ref to https://www.allaboutcircuits.com/technical-articles/introduction-temperature-sensors-thermistors-thermocouples-thermometer-ic/

and how do I choose a probe ?

And these thermocouple tables are handy. Note you need a cold junction to get the right temperatures.

and cold junction compensation explained extract from 030012.pdf
ie

extract from Therm_v1.pdf

And here is a complete circuit and coding :
