Adafruit Sensirion SHT31-D Temperature & Humidity Sensor

Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. The SHT31-D sensor offers an excellent ±2% relative humidity and ±0.3°C temperature accuracy. This version includes a PTFE filter, keeping the sensor clean while allowing humidity measurements to work effectively.

This sensor features a true I2C interface with two address options, and is compatible with both 3V and 5V power supplies, making it suitable for use with almost any microcontroller or microcomputer.

To facilitate quick integration, the sensor is mounted on a custom PCB with supporting circuitry including pull-up resistors and capacitors, designed in the STEMMA QT form factor. Dual STEMMA QT connectors provide seamless compatibility with SparkFun Qwiic I2C connectors, enabling solderless connections and easy chaining of multiple sensors and accessories.

Each purchase includes one fully assembled and tested PCB breakout and a small piece of header that requires soldering for use with solderless breadboards.
