Specific Notes:
1. Includes stress outside of recommended operating zone.
General Notes:
Sensor is ratiometric to supply voltage.
2. Device is tested at 3.3 Vdc and 25 C.
3. Non-condensing environment. When liquid water falls on
Extended exposure to >90 % RH causes a reversible shift
of 3 % RH.
the humidity sensor die, output goes to a low rail condition
indicating no humidity.
Sensor is light sensitive. For best performance, shield
sensor from bright light.
4. Total accuracy including interchangeability is 3 %RH.
