By reading the BME280 manual https://ae-bst.resource.bosch.com/media/_tech/media/datasheets/BST-BME280-DS002.pdf I have some questions I would like to clarify. Looking at figure 1 at page 10, I wonder what happens if the sensor is found outside the operating range? Is it getting destroyed? A temporary measurement offset is introduced? Should we be worried that a measurement offset is introduced when the sensor stays for long time in very high (>80%) or very mow (<20%) relative humidity?
Thank you very much for your help.

We do not expect the sensor to be damaged by such operations, but the sensing performance can be temporarily degraded. In such a case, we recommend following the reconditioning procedure (see chapter 7.9) to restore the humidity sensor's performance.
