outputs • Multi-function ASIC • RoHS andWEEE compliant, halogen-free

Honeywell HumidIcon™ Digital Humidity/Temperature Sensors are digital
output-type relative humidity (RH) andtemperature sensors combined in thesame package. They are available in thefollowing accuracies:±1.7 %RH (HIH9000 Series)±2.0 %RH (HIH8000 Series)±3.0 %RH (HIH7000 Series)±4.0 %RH (HIH6100 Series)±4.5 %RH (HIH6000 Series)

Benefits: Industry-leading long term
stability minimizes system performanceissues, helps support system uptime
by eliminating the need to service orreplace the sensor during its application
life, and eliminates the need to regularly
recalibrate the sensor in the application,
which can be inconvenient and costly.
Thermoset-polymer capacitive sensing
element’s multilayer construction provides
resistance to most application hazards
such as condensation, dust, dirt, oil, andcommon environmental chemicals, which
help provide industry leading reliability.
Delivers the lowest total cost solution due
to the sensor’s industry-leading combined
humidity/temperature sensor. Allows
the RH measurement to be temperaturecompensated and provides a second,
standalone temperature sensor output
which allows the user to purchase one
sensor instead of two. Can operate down
to 2.3 Vdc, which allows use in low energyFeatures: Industry-leading long termstability (1.2 %RH over five years)• Industry-leading reliability (MTTF
9,312,507 HR) • Lowest total cost solution• Combined humidity and temperaturesensor • Energy efficient • High resolution• True, temperature-compensateddigital I2C or SPI output • SOIC-8 SMD(Surface Mount Device) and SIP 4 Pin
housing styles • Available with or withouthydrophobic filter and condensation-

and wireless-compatible applications toenhance energy savings and prolong
system battery life. The sensor goes
into sleep mode when not taking ameasurement within the application,
consuming only 1 μA versus 650 μA in fulloperation in a battery operated system;
helps maximize battery life, reduces power
supply size, and reduces the application’s
overall weight. 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 digitalI2C or SPI output typically allows thecustomer to remove the components
associated with signal conditioning fromthe 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,
as well as simplifies integration to themicroprocessor, eliminating the need forcustomer-implemented, complex signalconditioning. Ultra-small size allows forflexibility of use within the application,
occupies less space on the PCB, andtypically simplifies placement on crowded
