Honeywell HumidIconTM Digital Humidity/Temperature Sensors: HIH6130/6131 Series GENERAL INFORMATION The following associated literature is available on the Web: Product data sheet 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 - 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 CAUTION CAUTION IMPROPER SOLDERING For better product reliability, the HIH6130/6131 Series is factory-shipped with a protective tape on the cover (sensing face). This tape must remain in place during soldering. After soldering, remove the protective tape as described below to activate the sensor. Failure to comply with these instructions may result in product damage. PROTECTIVE TAPE REMOVAL 1. Use proper ESD protection. 2. Using covered fingers or tweezers to ensure that no debris falls into the filter, sensor cover or die, grip the overhanging front edge of the protective tape and peel it back from the top surface of the sensor. 3. Ensure the complete rectangle of protective tape is removed. Figure 1. Protective Tape Removal IMPROPER HANDLING Do not remove the sensor from its original protective packaging until it is ready to be installed. Do not touch the sensor surface. Use latex finger cots. Handle the sensor by its package edges or leads. Do not allow objects to enter the cavity of the sensor element. Do not allow debris or contaminants to accumulate on the filter. Failure to comply with these instructions may result in product damage. SOLDERING AND ASSEMBLY CAUTION IMPROPER CLEANING Insert and solder the sensor after the PCB cleaning process. Failure to comply with these instructions may result in product damage. CAUTION IMPROPER SENSOR POSITIONING Position the sensor so that its face is exposed to the atmosphere being monitored. Failure to comply with these instructions may result in product damage. Sensing and Control SOLDERING Process Automated: Use a no-clean flux. Limit the contact of the flux to the leads only. Reflow soldering profile is specified by J-STD-020D for a small package with a peak temperature of 260 C [500 F]. Manual: Do not exceed 350 C [662 F] for 4 s max. HIH6130/6131 Series 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. Issue 3 50061154 To rehydrate the sensor, expose it to room temperature under ambient conditions (>50 %RH) for a minimum of five hours. MOISTURE SEALING THE LEADS If, in the presence of intermittent moisture or other contaminants, there is the possibility of galvanic paths between the leads, moisture seal the leads and exposed pads.

Accuracy is specified at the typical supply voltage of 3.3 Vdc and at 25 C [77 F]. It is the maximum deviation from the ideal transfer function of relative humidity measured over the humidity range of 10 %RH to 90 %RH and includes all errors due to humidity non-linearity, humidity hysteresis and humidity non-repeatability. 3. Total error band is the maximum deviation from the ideal transfer function of relative humidity over the compensated range of 5 C [41 F] to 50 C [122 F]. It includes all errors due to humidity non-linearity, humidity hysteresis, humidity non-repeatability, thermal effect on zero, thermal effect on span and thermal hysteresis. 2 Honeywell Sensing and Control HIH6130/6131 Series Issue 3 Table 3.
