// R25 = 100 kOhm, beta25 = 4092 K, 1 kOhm pull-up,
// 100k EPCOS (WITH 1kohm RESISTOR FOR PULLUP, R9 ON SANGUINOLOLU! NOT FOR 4.7kohm PULLUP! THIS IS NOT NORMAL!)
// Verified by linagee.
// Calculated using 1kohm pullup, voltage divider math, and manufacturer provided temp/resistance
// Advantage: Twice the resolution and better linearity from 150C to 200C
