and ±4.5 %RH (HIH6000 Series)
What makes our sensors better?
INDUSTRY-LEADING TOTAL ERROR BAND (TEB) (±5 %RH)*
Honeywell specifies Total Error Band—the most comprehensive, clear, and meaningful
measurement —that provides the sensor’s true accuracy of ±5 %RH over a compensated
range of 5 °C to 50 °C [41 °F to 122 °F] and 10 %RH to 90 %RH. TEB includes all errors
due to:
• Humidity non-linearity
• Humidity hysteresis
• Humidity non-repeatability
• Thermal effect on zero
• Thermal effect on span
• Thermal hysteresis

Total Error Band should not be confused with “accuracy”, which is actually a
component of Total Error Band. Many competitors simply specify the accuracy of their
device; however, the specification may exclude hysteresis and temperature effects,
and may be calculated over a very narrow range, at only one point in the range, or at
their absolute best accuracy level. It is then up to the customer to calibrate the device
to make sure it has the accuracy needed for the life of the application.
Honeywell’s industry-leading Total Error Band provides the following benefits to the customer:
•
Eliminates individually testing
and calibrating every sensor, which can increase their manufacturing time
and process.
• Supports system accuracy and warranty requirements.
• Helps to
optimize system uptime.
• Provides
excellent sensor interchangeability
— the customer can remove one sensor from the tape,
then remove the next sensor from the tape, and there is no part-to-part variation in accuracy.

“Explanation of the Total Error Band Specification for Honeywell’s Digital Humidity/
Temperature Sensors.”
INDUSTRY-LEADING LONG-TERM STABILITY
(1.2 %RH OVER FIVE YEARS)*
Competitive humidity sensors need to go through 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
provides the following benefits to the customer.
Honeywell’s industry-leading long-term stability provides the following benefits to the customer:
• Minimizes system performance issues.
• Helps support system uptime by eliminating the need to service or replace the sensor during its application life.
• Eliminates need to regularly recalibrate the sensor in their application, which can be inconvenient and costly.

OUTPUT*
This typically allows the customer to remove the components associated with signal
conditioning from the PCB to
free up space
and
reduce costs
associated with those
components (e.g., acquisition, inventory, assembly). True, temperature-compensated

C or SPI output often eliminates problems that could occur from having
multiple signal conditioning components across the PCB, as well as simplifies
integration to the microprocessor, eliminating the need for customer-implemented,

INDUSTRY-LEADING RELIABILITY*
HIH6130/6131 and HIH6120/6121 Series
sensors use a laser trimmed, thermoset
polymer capacitive sensing element. The
element’s multilayer construction provides
resistance to most application hazards
such as condensation, dust, dirt, oils, and
common environmental chemicals, which helps
provide industry-leading stability and reliability.

LOWEST TOTAL COST SOLUTION*
Honeywell’s HumidIcon HIH6100 Series offers customers the
lowest total cost
solution
due to the sensor’s industry-leading Total Error Band and its being a
combined humidity/temperature sensor.
One sensor does the work of two!
COMBINED HUMIDITY AND TEMPERATURE SENSOR
The humidity and temperature sensors are co-located in the same package. This
allows the RH measurement to be temperature compensated and provides a
second, standalone temperature sensor output. This allows the user to
purchase
one sensor instead of two.
ENERGY EFFICIENT*
•
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
650 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.

ULTRA-SMALL PACKAGE SIZE
SOIC-8 SMD (Surface Mount Device) and SIP 4 Pin packages are ultra small,
including the condensation-resistant versions with hydrophobic filter on-board
(HIH6121 and HIH6131). Allows for flexibility of use within the application,
occupies less space
on the PCB, and typically simplifies placement on crowded
PCBs or in small devices.
FILTER
Available with hydrophobic filter and condensation-resistance, allowing for
use in
many condensing environments,
or without hydrophobic filter, non-condensing.
TAPE AND REEL
Cost-effective tape-and-reel packaging allows for use in high volume, automated
pick-and-place manufacturing,
eliminating lead misalignment
to the PCB and
helping the customer to
reduce manufacturing costs.
WIDE OPERATING TEMPERATURE RANGE
-25 °C to 85 °C [-13 °F to 185 °F] allows for use in many applications.
OPTIONAL ONE OR TWO %RH LEVEL ALARM OUTPUTS
A feature of the HIH6130 and HIH6131, this provides the ability to monitor whether
the RH level has exceeded or fallen below predetermined and critical levels within
the application.
MULTI-FUNCTION ASIC
Delivers flexibility within the application by lowering or eliminating the risk and cost
of OEM calibration.
