Adafruit Sensiron SHT31-D Temperature & Humidity Sensor Breakout

Please note: We have a limited stock of the original, non-STEMMA version of this board.  Once these are gone we will only be able to stock the STEMMA version! If you require that version, please contact us!  

Sensiron Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And, finally we have some that have a true I2C interface for easy reading. The SHT31-D sensor has an excellent ±2% relative humidity and ±0.3°C accuracy for most uses.

Unlike earlier SHT sensors, this sensor has a true I2C interface, and (bonus!) even with two address options. It also is 3V or 5V compliant, so you can power and communicate with it using just about any microcontroller or microcomputer.

Such a lovely chip - so we spun up a breakout board with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors. Each order comes with one fully assembled and tested PCB breakout and a small piece of header. You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner.
