Honeywell HumidIcon
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

 HIH6121
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.
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.
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.
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.
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.
