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.

HDC3020EVM — 온도 및 습도 센서용 HDC3020 평가 모듈

HDC3020EVM 평가 모듈(EVM)을 사용하면 설계자는 HDC3020 상대 습도 및 온도 센서의 작동과 성능을 평가할 수 있습니다. EVM에는 MSP430F5528 마이크로컨트롤러(µC)와 HDC3020이 탑재되어 있습니다. µC는 HDC3020을 제어하고 USB 포트를 통해 호스트 PC와 통신하는 데 사용됩니다. EVM은 필요할 경우 두 개의 섹션으로 나눌 수 있도록 설계되었습니다. 천공으로 인해 사용자가 HDC3020을 분리하여 유연하게 평가할 수 있습니다.
