INDUSTRY-LEADING reliability * ACCuracy * packaging * long-term stability 2 sensing.honeywell.com Features and Benefits Industry-leading long-term stability* (1.2 %RH over five years) Competitive humidity sensors require 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: * Minimizes system performance issues 0 . 3 * 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 H %R ACY UR ACC 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, oils, and common environmental chemicals, which help provide industry-leading reliability Offers customers the lowest total cost solution. Lowest total cost solution* Honeywell's HumidIcon HIH7000 Series delivers the lowest total cost solution due to the sensor's industry-leading combined humidity/temperature sensor One sensor does the work of two! 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 A of power versus 750 A 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 *Competitive Differentiator sensing.honeywell.com 3 Features and Benefits 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 Free up PCB space. Reduce costs. 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, temperaturecompensated 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 customerimplemented, complex signal conditioning Choose options to best fit the application. 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 -40 C to 100 C [-40 F to 212 F] 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 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 RoHS and WEEE compliant, Halogen Free 4 sensing.honeywell.com Potential Applications INDUSTRIAL 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.

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.
