Datasheet

Here is the datasheet. Have a nice read!

Marlin/Sprinter firmware

On line 44. in Configuration.h (Marlin firmware):
#define TEMP_SENSOR_0 5

There is a short explanation on line 40:
// 5 is ParCan supplied 104GT-2 100K

Generating the temp table yourself

// ./createTemperatureLookup.py --r0=100000 --t0=25 --r1=0 --r2=4700 --beta=4267 --max-adc=1023
// r0: 100000
// t0: 25
// r1: 0
// r2: 4700
// beta: 4267
// max adc: 1023
#define NUMTEMPS 20
