Matematika ti je izuzetno prosta za to sto ti treba. Prema tvojim zahtevima pritisak dobijas na sledeci nacin:
Pritisak = (NaponAD - 0.5) / 8
NaponAD je napon koji se dobija konverzijom ocitanih AD jedinica u volte. Ako ti je AD konvertor rezolucuje 12 bit-a, a referntni napon je 5V, onda je:
NaponAD = AD * 5 / 4095
gde AD predstavljaju ocitane AD jedinice.

Pozdrav
