Potential Industrial Applications
Figures 1 through 6 show a variety of potential industrial applications in which these sensors may be used.
HVAC/R
May be used to provide
precise RH and temperature
measurement in air
conditioning/air movement
systems, enthalpy sensing,
thermostats, humidifiers/
dehumidifiers, 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 (see Figure 1).
AIR COMPRESSORS
May be used to provide
precise RH measurement in
compressed air lines, allowing
the system to remove any
condensation; dry compressed
air is critical for customer
process control measurement
(see Figure 2).
Sensing and Control
WEATHER STATIONS
May be used to provide
precise RH and temperature
measurement in ground-based
and airborne weather stations,
allowing real time and highly
accurate monitoring/reporting
of actual weather conditions
(see Figure 3).
TELECOM CABINETS
May be used to provide
precise 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 (see Figure 4).

INDUSTRIAL 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 (see Figure
5).
GRAIN DRYING SYSTEMS
May be used to help the
grain bin storage manager
uniformly maintain an optimum
level of relative humidity and
temperature in the silo (See
Figure 6).

HIH6100, HIH6000, HIH7000, HIH8000, HIH9000 Series Features and Benefits
( = competitive differentiator)
 Industry-leading long term stability (1.2 %RH over five years):
- 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 the application, which can be
inconvenient and costly
 Industry-leading reliability (MTTF 9,312,507 HR): Thermoset-polymer capacitive sensing
element’s multilayer construction provides resistance to most application hazards such as
condensation, dust, dirt, oil, and common environmental chemicals, which help provide industryleading reliability.
 Lowest total cost solution: Delivers the lowest total cost solution due to the sensor’s industryleading combined humidity/temperature sensor
• Combined humidity and temperature sensor: Allows the RH measurement to be temperature
compensated, and provides a second, standalone temperature sensor output; 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 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
• 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). 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.
 Housing style: SOIC-8 SMD (Surface Mount Device) or SIP 4 Pin; ultra small size 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; industry standard design simplifies design-in
• Filter: Available with hydrophobic filter and condensation-resistance, allowing for use in many
condensing environments, or without hydrophobic filter, non-condensing
• Tape and reel: 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: Allows for use in many applications
• Optional one or two %RH level alarm outputs: Provides the ability to monitor whether the RH
level has exceeded or fallen below pre-determined 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
• RoHS and WEEE compliant, halogen-free
