Digital Humidity/Temperature Sensors
Honeywell HumidIcon™ Digital Humidity/Temperature Sensors, HIH6100 Series, are digital output-type relative humidity (RH)
and temperature sensors combined in the same package. These sensors provide an accuracy level of ±4.0 %RH and a
temperature accuracy level of ±0.5 °C.

Industry-leading Total Error Band Energy efficiency
Industry-leading reliability Lowest total cost solution • Ultra-small package size and options
Other accuracies available: ±1.7 %RH (HIH9000 Series), ±2.0 %RH (HIH8000 Series), ±3.0 %RH (HIH7000 Series),
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

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.
For more information about Total Error Band, please see the related technical note,
“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.
TRUE, TEMPERATURE-COMPENSATED DIGITAL I2C OR SPI
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
digital I2C 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,
complex signal conditioning.
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.
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.

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.
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.
Offers customers the lowest total cost solution.
One sensor does the work of two!

HIGH RESOLUTION
High 14-bit humidity sensor resolution and 14-bit temperature sensor resolution
within the application help the user’s system detect the smallest relative
humidity or temperature change.
TRUE, TEMPERATURE-COMPENSATED
DIGITAL I2C OR SPI OUTPUT*
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). Often eliminates
problems that could occur from having multiple signal conditioning components
across the PCB. Simplifies integration to the microprocessor, eliminating the need
for customer-implemented, complex signal conditioning.
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

of OEM calibration.

NOTICE:
SENSOR REHYDRATION
Exposure to elevated temperatures, such as those
experienced during solder reflow, may dry out the sensing
element. It is recommended that the sensor be allowed time
to rehydrate after soldering or other high temperature/dry
exposures.
Exposure to these conditions will not permanently damage the
sensor. It will generally return to its factory-calibrated value after
rehydration.
If rehydration is not performed, the sensor may read a slight
offset that slowly disappears over time as the sensor becomes
exposed to ambient conditions. Conversely, extended
exposure to condensing and high humidity environments
(>90 %RH) may cause a revisable shift in readings which will
generally return to normal after the sensor has been allowed to
dry off.
To rehydrate the sensor, expose it to room temperature under
ambient conditions (>50 %RH) for a minimum of five hours.
