As of April 6, 2021, we’ve updated this sensor to be STEMMA QT compatible – that means there’s now an easy way to plug-and-play this sensor without any soldering! The physical shape has changed a little, and the pinout has changed to our QT standard ordering.
Sensirion 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. We now use the version with a PTFE filter, it’ll stay clean while still allowing humidity measurements to work
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.
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 to use with a solderless breadboard. but it’s fairly easy and takes only a few minutes even for a beginner.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
