Introduction

Looking to keep a log of the climate in your greenhouse, create a humidor control system or want to track temperature and humidity data for a weather station project? The SparkFun Humidity Sensor Breakout - SHTC3 (Qwiic) may be the perfect option for you! The SHTC3 is a low cost, easy-to-use, highly accurate digital humidity and temperature sensor. The SHTC3 communicates via I2C so, as you can tell by the name, we have broken out the pins on the sensor to Qwiic connectors so you can easily connect it to SparkFun's ever growing Qwiic Ecosystem.
