NTC thermistor calculation for sketch

Hi ,

I'm trying to build a sketch to read the temperature from the NTC thermistor include in the "Starter Kit"

When I just plug it on my Uno and read the serial, I can see than the values goes down when the temp becomes higher, and up when temp because cold, and well that's normal due to his internal process !
But I want now to have the right temperature in °C, and so for that I need the calculation + code to put in my sketch, have you got more infos ? can't find these answers in the .pdf of this device...

Many thanks for your revert

Nicolas

Hello nicox

Thanks for your question.

If you follow this link (http://www.giangrandi.ch/electronics/ntc/ntc.shtml) you could find a
NTC temperature calculator.

All NCT behave in the same way following the same equation. You could find the information in this link.

Regards and best wishes.
