HDC2080: Bake/Re-Hydration Procedure

Part Number: HDC2080

Hi Team,

The datasheet shows the following about Bake/Re-Hydration Procedure.

11.1.1.5 Bake/Re-Hydration Procedure
Prolonged exposure to extreme conditions or harsh contaminants may impact sensor performance. In the case
that permanent offset is observed from contaminants, the following procedure is suggested, which may recover
or reduce the error observed in sensor performance:
1. Baking: 100°C, at less than 5%RH, for 5 to 10 hours
2. Re-hydration: Between 20°C to 30°C, 60%RH to 75%RH, for 6 to 12 hours

Is it possible to extend the yellow part?
Is it required to control strict time?

Best Regards,
Yaita

    Hi Yaita,

    The recommended time on the datasheet is the minimum time required for the sensor to recover. You can extend the bake and re-hydration times as long as the temperature and humidity conditions match the datasheet specifications. 

    If you do want to extend the bake time, please try to limit it to 24 hours.
