Honeywell introduced the new HumidIcon(tm) Digital Humidity/Temperature Sensors, HIH-6130/6131 Series, offering industry- leading accuracy, stability, and energy efficiency in a lowest total cost solution that combines digital output relative humidity and temperature sensing. This new product is designed for potential use in HVAC-refrigeration, respiratory therapy, medical incubators, and medical microenvironment applications.
Honeywell HumidIcon™ Digital Humidity/Temperature Sensors have an industry-leading Total Error Band that provides the sensor's true accuracy of ±5 %RH over a compensated temperature range of 5 °C to 50 °C [41 °F to 122 °F] and 10 %RH to 90 %RH. Total Error Band, which includes all sources of error that a sensor might see, effectively eliminates individual sensor testing and calibration, supports system accuracy and warranty requirements, helps to optimize system uptime, and provides excellent sensor interchangeability.
The new series offers industry-leading long-term stability of 1.2 %RH over five years. Many 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. The Honeywell HumidIcon™ device only requires a 5-hour rehydration process under ambient conditions (>50 %RH). This long term stability minimizes system performance issues, helps support system uptime by eliminating the need to service or replace the sensor during its application life, and eliminates the need to regularly recalibrate the sensor in the application, which can be inconvenient and costly.
The Honeywell HumidIcon™ sensor can operate down to 2.3 Vdc, which allows for use in low energy and wireless-compatible applications to enhance energy savings and prolong system battery life. This low operating voltage also means 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 maximizes battery life, reduces power supply size, and reduces the application's overall weight. 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
The ultra-small SOIC-8 SMD (Surface Mount Device) package comes in two configurations: the HIH-6130 (no filter, non-condensing) and the HIH-6131 (hydrophobic filter and condensation-resistant), which allow for use in many condensing environments. Cost-effective tape-and-reel packaging 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.
