Automotive ±0.5% RH accurate analog-output humidity sensor

The HDC3120-Q1 is an integrated, capacitive based relative humidity (RH) and temperature sensor where the relative humidity and temperature sensor results are represented as ratiometric analog output. Conversion of signals to the analog domain provides a robust design for applications requiring signal transmission over wire or other distance-based use cases. The device provides high accuracy measurements over a wide supply range (1.62V – 5.5V) and low power consumption while maintaining less than 0.19% long term drift per year. The HDC3120-Q1 is available in a compact 2.5mm × 2.5mm × 0.8mm WSON 8-pin package. Both the temperature and humidity sensors are 100% tested and calibrated on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 standards.
