Do you have any correlating numbers on the effect ?
(Did you say that you see a 1% increase in the
sensor output voltage in the case of high humidity
with the Miniox ?).

What about condensation inside the sensor ?
Is this a problem in your design ?

Does the O2 hysteresis of the sensor change
with the humidity level ?

If the humidity level can vary a bit one could
(for educational purposes at this point) ) integrate
a humidity sensor and the O2 sensor (and what the heck,
add a temperature sensor too) into one package.  Trouble is,
the humidity sensors I have seen  all respond much faster to
changes in the humidity than does the O2 sensors.  It's
important to point out that I do not have first hand data
on this aspect of O2 sensors.
