HDC2022DEPR 2 Applications

• Thermostats • Smart speakers (with voice assistant) • Washers and dryers • HVAC sensor transmitters (temperature, pressure,and humidity) • HVAC system controllers • Wireless environmental sensorsThe HDC2022 is an integrated relative humidity andtemperature sensor with a factory-installed PTFEmembrane cover over the opening of the relativehumidity sensor. The cover is a hydrophobicmicropourous PTFE foil that protects against dust andwater according to IP67 specifications. The cover isdesigned to adhere to the package over lifetimeoperation while maintaining the same response timeas a sensor without the membrane. The cover has afiltration efficiency of 99.99% down to a particle size of100 nm.The HDC2022 device is backward-compatible with theHDC2080, providing high accuracy measurementswith very low power consumption in a small DFNpackage. The capacitive-based sensor includes newintegrated digital features and a heating element todissipate condensation and moisture. The HDC2022digital features include programmable interruptthresholds to provide alerts and system wake-upswithout requiring a microcontroller to continuouslymonitor the system. Combined with programmablesampling intervals, low power consumption, and 1.8-Vsupply voltage support, the HDC2022 is designed forultra-low power battery-operated systems.Device InformationTypical ApplicationRH Accuracy (TA = 30°C)
