Adafruit HDC3022 Precision Temperature & Humidity Sensor - STEMMA QT / Qwiic

The Adafruit HDC3022 Precision Temperature & Humidity Sensor breakout offers industry-leading accuracy and precision with the TI HDC302x series chip. Featuring ±0.5% typical accuracy for relative humidity and ±0.1°C for temperature measurement, this sensor is ideal for precise environmental monitoring projects.

This upgraded HDC3022 sensor includes a white PTFE filter cover for sensor protection and cleanliness. The device supports a true I2C interface with selectable addresses for multiple sensors on one bus, operates safely from 1.8V to 5.5V, and provides low power consumption with advanced features like programmable interrupts and offset correction.

Designed for ease of use, this breakout board includes supporting circuitry and STEMMA QT / SparkFun Qwiic compatible connectors for plug-and-play integration without soldering. A small piece of header is included for breadboard use. Comprehensive Arduino and CircuitPython libraries are available for easy implementation.
