Honeywell Humidity Sensor - HIH9000 Series

1. Description of HIH9000 Series Humidity Sensor:

The HumidIcon™ digital humidity/temperature sensor is an integrated sensor that packages a digital output relative humidity (RH) sensor and a temperature sensor together.

Available models with the following accuracies:

• ±1.7 %RH (HIH9000 series)

• ±2.0 %RH (HIH8000 series)

• ±3.0 %RH (HIH7000 series)

• ±4.0 %RH (HIH6100 series)

• ±4.5 %RH (HIH6000 series)

2. Features of HIH9000 Series Humidity Sensor：

• Long-term stability (maintains 1.2 %RH for over 5 years)
• Greatly reduces performance issues
• No need for sensor maintenance or replacement during its service life, helping to extend system uptime
• Eliminates the need for periodic sensor calibration in applications, reducing workload and cost
• Reliability (MTTF 9,312,507 HR):The multilayer construction of the thermoset polymer capacitive sensing element withstands most application hazards such as condensation, dirt, dust, oil, and common environmental chemicals, helping to provide industry-leading reliability.
• Lowest total cost solution:Because this sensor offers the industry's combined humidity/temperature sensor, it provides the lowest total cost solution.
• Combined humidity and temperature sensor:This allows relative humidity measurements to be temperature compensated and provides a second independent temperature sensor output, allowing users to purchase only one sensor instead of two.
• Energy saving:
• Low supply voltage:Operates at DC voltages as low as 2.3 Vdc, enabling use in low-power and wireless-compatible applications, improving energy efficiency and extending system battery life
• Low power consumption:When not measuring in the application, the sensor enters sleep mode, consuming only 1 µA, while fully operational in battery-powered systems it consumes 650 µA; sleep mode helps maximize battery life, reduce power supply size, and lower overall application weight
• High resolution:The humidity sensor used in the application provides 14-bit high resolution, and the temperature sensor also provides 14-bit resolution, helping user systems detect very small relative humidity or temperature changes
• True effective temperature-compensated digital I2C or SPI output:This allows customers to remove signal conditioning components from the PCB, freeing up board space and reducing costs associated with these components (e.g., procurement, inventory, assembly). True effective temperature-compensated digital I2C or SPI output typically avoids issues from placing multiple signal conditioning elements on the PCB while simplifying integration with microprocessors, eliminating the need for complex signal conditioning by customers.
• Housing type:SOIC-8 SMD (surface mount device) or SIP 4-pin: ultra-small size provides flexibility in applications, occupies less space on the PCB, simplifying layout in crowded PCBs or small devices; industry-standard design simplifies embedded design
• Filter:Optional hydrophobic filter that is condensation-resistant, suitable for various condensing environments, or without hydrophobic filter for non-condensing environments
• Tape and reel:Suitable for high-volume, automated pick-and-place manufacturing, eliminating wire misalignment on the PCB and helping customers reduce production costs.
• Wide operating temperature range:Can be used in many applications
• Optional one or two %RH alarm outputs:Enables monitoring whether RH levels exceed or fall below predetermined and critical levels in the application
• Versatile ASIC:Enhances flexibility in applications by reducing or eliminating OEM calibration risk and cost
• RoHS and WEEE compliant, halogen-free
