Adafruit Sensirion SHTC3 Temperature and Humidity Sensor features a true I2C interface that provides interfacing with only two wires (plus power and ground). This sensor offers ±2% relative humidity, ±0.2°C accuracy, and has an I2C interface on address 0x70. The SHTC3 sensor has a breakout board, supporting circuitry such as pullup resistors and capacitors, and Qwiic compatible STEMMA QT connectors for the I2C bus. The breakout board also includes a voltage regulator and level-shifting circuitry.
