Specific Notes:
1. Applies to HIH-4602-L-CP 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.
