Offering industry-leading long-term accuracy, stability, and reliability, Honeywell's new 6000, 7000, 8000, and 9000 Series of the HumidIcon combination digital output RH and thermal sensor solutions have been made available today. Featuring true, temperature compensated digital I2C or SPI output, the new sensors are targeted for medical, HVAC, and industrial applications and provide a cost effective solution for device and system developers.

The Honeywell HumidIcon sensor’s proven accuracy eliminates the need for individual test and calibration as there is no part-to-part variation in accuracy, which shortens manufacturing time. Industry-leading, long-term stability 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. 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 only requires a five-hour rehydration under ambient conditions (>50 %RH).

True, temperature-compensated digital I2C or SPI output allows the customer to remove the components associated with signal conditioning from the PCB to free up space and reduce the costs associated with those components (e.g., acquisition, inventory, assembly). True, temperature-compensated digital I2C or SPI output also 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 customer-implemented, complex signal conditioning.

The HumidIcon™ Series (6000, 7000, 8000, and 9000) offers customers the ability to choose housing style (SIP 4-Pin or SOIC-8 SMD), filter (hydrophobic filter or no filter), output (I2C or SPI), and packaging (tape and boxed, tape and reel, or samples on tape). Refer to the HumidIcon™ datasheets for information regarding specifications for each.

“Honeywell’s HumidIcon™ Series delivers the lowest total cost solution due to the sensor’s industry-leading combined humidity/temperature sensor,” said Jacqueline Leff, Honeywell senior global product marketing manager. “It allows the RH measurement to be temperature compensated, and provides a second standalone temperature sensor output allowing the user to purchase one sensor instead of two.”
