Honeywell HumidIcon™ Digital Humidity/Temperature Sensors: HIH-6130/6131 Series 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, remove the next sensor from the tape, and there is no part-to-part variation in accuracy DESCRIPTION ( = competitive differentiator) Honeywell HumidIcon™ Digital Humidity/Temperature Sensors: HIH-6130/6131 Series, is a digital output-type relative humidity (RH) and temperature sensor combined in the same package. These devices offer several competitive advantages, including: Industry-leading Total Error Band Industry-leading stability Industry-leading reliability Lowest total cost solution 2 True temperature-compensated digital I C output Energy efficiency Ultra-small package 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: 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 their application, which can be inconvenient and costly Industry-leading reliability: Honeywell’s new HIH6130/6131 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 help provide industry-leading stability and reliability. Honeywell HumidIcon™ Digital Humidity/Temperature Sensors Lowest total cost solution: Offers customers the lowest total cost solution due to the sensor’s industryleading Total Error Band and its being a combined humidity/temperature sensor. True, temperature-compensated digital I C 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 customerimplemented, complex signal conditioning. Energy efficient Low supply voltage: Can operate down to 2.3 Vdc, which allows use in low energy and wirelesscompatible 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. 2 Ultra-small package: SOIC-8 SMD (Surface Mount Device) package is ultra small, including the condensation-resistant model with hydrophobic filter onboard (HIH-6131). 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. 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. Tape and reel packaging: Cost-effective tape-and-reel packaging allows for use in high volume, automated pickand-place manufacturing, eliminating lead misalignment to the PCB and helping the customer to reduce manufacturing costs. 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. 2 www.honeywell.com/sensing FEATURES AND BENEFITS Wide operating temperature range of -25 °C to 85 °C [-13 °F to 185 °F] allows for use in many applications Optional one or two %RH level alarm outputs provide the user the ability to monitor whether the RH level has exceeded or fallen below pre-determined and critical levels within the application Multi-function ASIC provides flexibility within the application by lowering or eliminating the risk and cost of OEM calibration Industry-standard package provides easy design-in RoHS and WEEE compliant; halogen-free Two configurations increase flexibility of use: HIH-6130: no filter, non-condensing; HIH-6131: hydrophobic filter and condensation-resistant allow use in many condensing environments POTENTIAL APPLICATIONS HVAC/R: May be used to provide precision RH and temperature measurement in air conditioning/air movement systems, enthalpy sensing, thermostats, humidifiers/de-humidifiers, 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. Respiratory therapy: May be used to provide precision RH and temperature measurement in sleep apnea machines and ventilators, enhancing patient comfort, safety and treatment effectiveness with warm and humidified air. 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. Air compressors: May be used to provide precision RH measurement in compressed air lines, allowing the system to remove any condensation; dry compressed air is critical for customer process control measurement. Weather stations: May be used to provide precision RH and temperature measurement in ground-based and airborn weather stations, allowing real time and highly accurate monitoring and reporting of actual weather conditions. Telecom cabinets: May be used to provide precision 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.

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 factorycalibrated 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.
