The working range of the humidity sensors HC104-Kxx
is shown with regard to the humidity / temperature limits.
Although the sensors would not fail beyond the limits, the
specification is guaranteed only within the working
range.
In
applications
with
high
humidity
at
high
temperatures the time factor shall be considered.
