Presumably only the slot needs to be exposed for humidity, covering the rest of the chip in thick rubber would slow down it's response to temperature changes, but I hope all its edges are at least covered in a thinner lacquer?
mcrossley:

I understand you concerns, but according the manufacturer specs http://www.sensirion.com/fileadmin/user ... eet_V5.pdf (Page 4, section 1.7) only the top window is need to be exposed to elements.

Also, the whole sensor family can be seen at: http://www.sensirion.com/en/products/hu ... mperature/

EDIT: I forgot to mention, the window senses both temperature & humidity.
