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.
