The HDC302x is an integrated capacitive based relative humidity (RH) and temperature sensor. It provides high accuracy measurements over a wide supply range (1.62 V – 5.5 V), along with ultra-low power consumption in a compact 2.5-mm × 2.5-mm package. Both the temperature and humidity sensors are 100% tested and trimmed on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 standards.

Offset Error Correction reduces RH sensor offset due to aging, exposure to extreme operating conditions, and contaminants to return device to within accuracy specifications. For battery IoT applications, auto measurement mode and ALERT feature enable low system power by maximizing MCU sleep time. There are four different I2C addresses that support speeds up to 1 MHz. A heating element is available to dissipate condensation and moisture.

The HDC3020 is an open cavity package without protective cover. Two device variants have a cover option to protect the open cavity RH sensor: HDC3021 and HDC3022. HDC3021 has removable protective tape to allow conformal coatings and PCB wash. HDC3022 has a permanent IP67 filter membrane to protect against dust, water and PCB wash.
