Specific Notes:

1. Can only be achieved with the supplied slope and offset. For

HIH-4030/31-003 catalog listings only.

2. Includes testing outside of recommended operating zone.

3. Includes testing for recommended operating zone only.

4. Device is calibrated at 5 Vdc and 25

ºC.

5. Non-condensing environment. When liquid water falls on the

humidity sensor die, output goes to a low rail condition

indicating no humidity.

General Notes:

• Sensor is ratiometric to supply voltage.

• Extended exposure to >90% RH causes a reversible

shift of 3% RH.

• Sensor is light sensitive. For best performance, shield

sensor from bright light.
