I got a thermistor temperatur sensor, and I have measured resistance at different temperatures.
3c = 25000 ohm 25c = 10000 ohm 33c = 6100 ohm 70c = 2100 ohm 100c = 960 ohm
and then I used Thermistor Calculator to calculate
and used "The Elaborate Code (cleaned up a bit)" LINK
my question is, should I always use a 10k resistor, or how do I know what size I need?
