Backward-compatible with HDC2080
The HDC2021 is an integrated relative humidity and temperature sensor with a factory-installed polyimide tape cover over the opening of the relative humidity sensor element. The tape cover provides protection against pollutants that can appear in certain stages of the manufacturing process, such as SMT assembly, PCB board wash, and conformal coating. The tape design allows for a full conformal coating of the PCB, and includes an adhesive free corner tab for quick removal using tweezers.
The device is backward-compatible with the HDC2080, providing high accuracy measurements with very low power consumption in a small DFN package. The capacitive-based sensor includes new integrated digital features and a heating element to dissipate condensation and moisture. The digital features include programmable interrupt thresholds to provide alerts and system wake-ups without requiring a microcontroller to continuously monitor the system. Combined with programmable sampling intervals, low power consumption, and 1.8-V supply voltage support, the is designed for ultra-low power battery-operated systems.
