Why not just use a thermistor? It's made for that purpose, already calibrated, costs a dollar or so, is tiny snd rugged, and can be read with a simple ohmmeter.

Wow
all sorts of web sources explaining how to measure temp with diodes and transistors.

A transistor with two of three legs soldered together makes a temperature probe. Is
the temperature inside of lam too hot? Google for temperature probe circuits like I
do for other projects.
