Features
and Benefits
InduStRy-leAdIng lOng-teRm StAbIlIty*
(1.2 %RH OveR FIve yeARS)
Competitive humidity sensors require a 12 hour at 75 %RH rehydration process
(which requires special equipment chambers) to correct reflow temperature
offset. Honeywell’s sensor also experiences an offset after reflow; however, it only
requires a five-hour rehydration under ambient conditions (>50 %RH).
Honeywell’s industry-leading long-term stability:
• Minimizes system performance issues
• Helps support
system uptime
by eliminating the need
to service or replace the sensor during its application life
•
eliminates the need to regularly recalibrate
the
sensor in the application, which can be inconvenient
and costly

•
Low supply voltage:
Can operate down to 2.3 Vdc, which allows use in
low
energy and wireless-compatible applications
to enhance energy savings
and prolong system battery life
•
Low power consumption:
The sensor goes into
sleep mode
when not
taking a measurement within the application, consuming only 1 µA of power
versus 750 µA in full operation in a battery operated system; sleep mode helps
maximize battery life, reduces power supply size, and reduces the application’s
overall weight
