Honeywell HumidIconTM Digital Humidity/Temperature Sensors: HIH6130/6131 and HIH6120/6121 Series DESCRIPTION ( = competitive differentiator) Honeywell HumidIconTM Digital Humidity/Temperature Sensors: HIH6130/6131 and 6120/6121 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 long-term stability Industry-leading Total Error Band Industry-leading reliability Lowest total cost solution 2 True temperature-compensated digital I C or SPI output Energy efficiency Ultra-small package 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 Total Error Band (TEB) (5 %RH) (See Figure 1): 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 Figure 1. Total Error Band Errors Humidity Non-Linearity + Humidity Hysteresis = Accuracy + Humidity Non-Repeatability + = Total Error Band 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. 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 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." Honeywell HumidIconTM Digital Humidity/Temperature Sensors Industry-leading reliability: Honeywell's new 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 help provide industryleading stability and reliability. 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 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 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 A of power versus 650 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. 2 Ultra-small package: 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. 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. 2 www.honeywell.com/sensing 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. FEATURES AND BENEFITS 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 (HIH6130/6131 only): 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: HIH6120 and HIH6130: no filter, non-condensing HIH6121 and HIH6131: hydrophobic filter and condensation-resistant allow use in many condensing environments 2 Optional I C or SPI digital communication formats: Provide the user with flexibility in integrating the sensors into existing system level architecture 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.

Honeywell Sensing and Control 9 Honeywell HumidIconTM Digital Humidity/Temperature Sensors SENSOR REHYDRATION 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 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. 10 www.honeywell.com/sensing ADDITIONAL INFORMATION The following associated literature is available on the Web: Product installation instructions Product application note Application sheets: - Humidity Sensor Performance Characteristics - Humidity Sensor Theory and Behavior - Humidity Sensor Moisture and Psychrometrics - Humidity Sensor Chemical Resistivity - Thermoset Polymer-based Capacitive Sensors Technical Notes: 2 - I C Communication with the Honeywell HumidIconTM Digital Humidity/Temperature Sensors - SPI Communication with the Honeywell HumidIconTM Digital Humidity/Temperature Sensors - Using Alarms on the Honeywell HumidIconTM Digital Humidity/Temperature Sensors - Entering and Using Command Mode on the Honeywell HumidIconTM Digital Humidity/Temperature Sensors - Total Error Band Specification for Honeywell Digital Humidity/Temperature Sensors WARNING WARNING MISUSE OF DOCUMENTATION The information presented in this product sheet is for reference only.
