The HDC3120 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 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.
