25 // 100k ATC Semitec 104GT-2 (Used on ParCan) (WITH 1kohm RESISTOR FOR PULLUP, R9 ON SANGUINOLOLU! NOT FOR 4.7kohm PULLUP! THIS IS NOT NORMAL!)
26 // Verified by linagee. Source: http://shop.arcol.hu/static/datasheets/thermistors.pdf
27 // Calculated using 1kohm pullup, voltage divider math, and manufacturer provided temp/resistance
28 // Advantage: More resolution and better linearity from 150C to 200C
