Adafruit Sensirion SHTC3 Temperature & Humidity Sensor - STEMMA QT / Qwiic

The Adafruit Sensirion SHTC3 sensor is a highly accurate temperature and humidity sensor with a true I2C interface for easy connectivity. Featuring ±2% relative humidity and ±0.2°C temperature accuracy, it is suitable for a wide range of applications.

This breakout includes the SHTC3 sensor along with supporting circuitry such as pull-up resistors and capacitors. The board is 3V and 5V compliant and comes with STEMMA QT / Qwiic connectors, allowing solderless connection with compatible cables.

Each purchase includes a fully assembled, tested PCB breakout and a small piece of header for soldering if you wish to use it on a breadboard. Arduino and CircuitPython libraries are available for easy interfacing.
