Digital Humidity/Temperature Sensor - HIH8000 Series

2. Features of Digital Humidity/Temperature Sensor HIH8000 Series

• Industry-leading long-term stability (1.2 %RH for over 5 years):

• Minimizes 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

• Industry-leading reliability (MTTF 9,312,507 HR):The multi-layer construction of the thermoset polymer capacitive sensing element withstands most application hazards such as condensation, dirt, dust, oil, and common environmental chemicals, contributing to industry-leading reliability.

• Lowest total cost solution:Due to its industry-leading combined humidity/temperature sensor, it provides the lowest total cost solution.

• Combined humidity and temperature sensor:This provides temperature compensation for relative humidity measurements and 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 active 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 the user's system detect very small changes in relative humidity or temperature

• True digital I2C or SPI output with temperature compensation:This allows customers to remove signal conditioning components from the printed circuit board, freeing up board space and reducing costs associated with these components (e.g., procurement, inventory, assembly). True digital I2C or SPI output with temperature compensation typically avoids issues from placing multiple signal conditioning elements on the PCB and simplifies integration with microprocessors, eliminating the need for complex signal conditioning by the customer.

• Housing types:SOIC-8 SMD (surface mount device) or SIP 4-pin: Ultra-small size allows flexible use 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 and condensation-resistant, suitable for various condensing environments, or without hydrophobic filter for non-condensing environments

• Tape and reel:Available 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 of RH levels exceeding or falling below predetermined and critical levels in the application

• Versatile ASIC:Enhances flexibility in applications by reducing or eliminating the risk and cost of OEM calibration

• RoHS and WEEE compliant, halogen-free
