- Tue Apr 12, 2016 8:28 am #45358 so if im understanding this correctly, I actualy need 2 voltgate divider circuits, one to drop the VCC ( say 3.3vdc) to 1vdc, and then a second to bias the thermistor.
say 220 and 100 0hm to get to 1 vdc.
that will feed my thermistor and a 10k to gnd.

10k because my sensor to 10k at 77 deg f
