HIH Temperature Compensation

The Huneywell HIH humidity sensors have mild temperature variance in their measured relative humidity. The generic "humidity" uses the HIH-36XX calculation. Humidit4000 uses the calculation on the right.

According to the datasheets:


RH = (Raw RH) /  ( 1.0546 - .00216 T ) 

T in Centigrade

RH = (Raw RH) /  ( 1.0305 + .000044 T - .0000011 T2

T in Centigrade
