Overview

Honeywell HumidIcon™ Digital Humidity/Temperature Sensor: HIH6100 Series, I2C, ±4.0 %RH accuracy, SIP 4 Pin, with filter, condensation-resistant, five units on tape (sample).

Honeywell HumidIcon™ Digital Humidity/Temperature Sensors: HIH6120/6121 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
  • True temperature-compensated digital I2C 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. The Honeywell sensor also experiences an offset after reflow; however, it only requires a five hour rehydration under ambient conditions (>50 %RH). The industry-leading Honeywell 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)
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

Industry-leading reliability
The new Honeywell 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 helps provide industry-leading stability and reliability.

Lowest total cost solution
Offers customers the lowest total cost solution due to the sensor's industry-leading Total Error Band and its being a combined humidity/temperature sensor.

True, temperature-compensated digital I2C 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 customer-implemented, complex signal conditioning.

Energy efficient

  • Low supply voltage: Can operate down to 2.3 Vdc, which allows use in low energy and wireless-compatible 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.

Ultra-small package
SIP 4 Pin packages are ultra small, including this condensation-resistant version with hydrophobic filter on-board. 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 pick-and-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.
