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 long-term stability • True temperature-compensated digital I2C or SPI output

• 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

• 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.

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.

Features

and Beneﬁts

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!

sensing.honeywell.com

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

Delivers flexibility within the application by lowering or eliminating the risk and cost

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.
