Honeywell HumidIcon™
Digital
Humidity/Temperature
Sensors: HIH-6130/6131
Series
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,
remove the next sensor from the tape, and there is no
part-to-part variation in accuracy
DESCRIPTION ( = competitive differentiator)
Honeywell HumidIcon™ Digital Humidity/Temperature
Sensors: HIH-6130/6131 Series, is a digital output-type relative
humidity (RH) and temperature sensor combined in the same
package. These devices offer several competitive advantages,
including:
Industry-leading Total Error Band
Industry-leading stability
Industry-leading reliability
Lowest total cost solution
2
True temperature-compensated digital I C output
Energy efficiency
Ultra-small package

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.
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:
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 their application, which can be inconvenient and
costly

Industry-leading reliability: Honeywell’s new HIH6130/6131 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
help provide industry-leading stability and reliability.
Honeywell HumidIcon™ Digital Humidity/Temperature Sensors

Lowest total cost solution: Offers customers the
lowest total cost solution due to the sensor’s industryleading Total Error Band and its being a combined
humidity/temperature sensor.

True, temperature-compensated digital I C 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 customerimplemented, complex signal conditioning.

Energy efficient
Low supply voltage: Can operate down to 2.3 Vdc,
which allows use in low energy and wirelesscompatible 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.

2
Ultra-small package: SOIC-8 SMD (Surface Mount
Device) package is ultra small, including the
condensation-resistant model with hydrophobic filter onboard (HIH-6131). 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.
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.
Tape and reel packaging: Cost-effective tape-and-reel
packaging allows for use in high volume, automated pickand-place manufacturing, eliminating lead misalignment to
the PCB and helping the customer to reduce
manufacturing costs.
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.

FEATURES AND BENEFITS
Wide operating temperature range of -25 °C to 85 °C
[-13 °F to 185 °F] allows for use in many applications
Optional one or two %RH level alarm outputs provide
the user the ability to monitor whether the RH level has
exceeded or fallen below pre-determined and critical
levels within the application
Multi-function ASIC provides flexibility within the
application by lowering or eliminating the risk and cost of
OEM calibration
Industry-standard package provides easy design-in
RoHS and WEEE compliant; halogen-free
Two configurations increase flexibility of use: HIH-6130:
no filter, non-condensing; HIH-6131: hydrophobic filter and
condensation-resistant allow use in many condensing
environments
POTENTIAL APPLICATIONS
HVAC/R: May be used to provide precision RH and
temperature measurement in air conditioning/air
movement systems, enthalpy sensing, thermostats,
humidifiers/de-humidifiers, and humidistats to maintain
occupant comfort and ideal storage humidity/temperature
while achieving low energy consumption, supporting
system accuracy and warranty requirements, maximizing
system uptime, and improving overall system quality.
Respiratory therapy: May be used to provide precision
RH and temperature measurement in sleep apnea
machines and ventilators, enhancing patient comfort,
safety and treatment effectiveness with warm and
humidified air.
Incubators/microenvironments: May be used to provide
optimal temperature and RH levels to support critical
processes and experiments, enhancing process efficiency
with desired climate conditions.
Air compressors: May be used to provide precision RH
measurement in compressed air lines, allowing the system
to remove any condensation; dry compressed air is critical
for customer process control measurement.
Weather stations: May be used to provide precision RH
and temperature measurement in ground-based and airborn weather stations, allowing real time and highly
accurate monitoring and reporting of actual weather
conditions.
Telecom cabinets: May be used to provide precision RH
and temperature measurement in the telecom cabinet
HVAC system; maintaining proper temperature and
humidity levels in the cabinet provides maximum system
uptime and performance.

SENSOR REHYDRATION
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 factorycalibrated 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.
