Honeywell HumidIcon™ Digital Humidity/Temperature Sensors

Industry-leading reliability: Honeywell’s new
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 help provide industry-
leading stability and reliability.
Lowest total cost solution: 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.
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.
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: 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.
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 pick-
and-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: -25 °C to 85 °C
[-13 °F to 185 °F] allows for use in many applications
Optional one or two %RH level alarm outputs
(HIH6130/6131 only): 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:
HIH6120 and HIH6130: no filter, non-condensing
HIH6121 and HIH6131: hydrophobic filter and
condensation-resistant allow use in many condensing
environments
Optional I2C or SPI digital communication formats:
Provide the user with flexibility in integrating the sensors
into existing system level architecture
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 air-
born weather stations, allowing real time and highly
accurate monitoring/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.
