About this item

The Adafruit HDC3021 Precision Temperature & Humidity Sensor breakout delivers high-accuracy environmental sensing for a variety of projects. It features the TI HDC302x chip, providing ±0.1 °C temperature accuracy and ±0.5 % relative humidity precision, with minimal long-term drift (~0.19 % RH per year). It interfaces via I²C (up to 1 MHz) and supports four selectable addresses, allowing multiple sensors on a single bus. Operating across a wide voltage range (1.62–5.5 V), it's compatible with various microcontrollers without level shifters. The breakout includes STEMMA QT connectors and easy-to-use Arduino/CircuitPython libraries, enabling rapid integration into IoT, home automation, and industrial monitoring systems.
