Specific Notes:
1. Can only be achieved with the supplied slope and offset.
For HIH-4000-003 and HIH-4000-004 catalog listings only.
2. Device is calibrated at 5 Vdc and 25 ºC.
3. Non-condensing environment.
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.
FACTORY CALIBRATION DATA
