b. For 5 V sensors
V
a
= (V
r
/ 256) * 3.3 * 2
Where V
a
= actual voltage
V
r
= “raw” sensor reading
e.g.: if sensor 0x44 says 0xC3 (195 decimal), the actual voltage is
(195/256) * 3.3 * 2 = 5.027 V.
c. For Temp sensors
T
a
= T
r
Where T
a
= actual temperature in
o
C
T
r
= “raw” sensor reading
e.g.: if sensor 0x61 says 0x1f (31 decimal), the actual temperature is
31
