And, finally we have some that have a true I2C interface for easy reading.\u003c\/p\u003e\n\u003cp\u003eThe 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\u003c\/p\u003e\n\u003cp\u003eUnlike 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.\u003c\/p\u003e\n\u003cp\u003eTo get you going fast, Adafruit spun up a custom made PCB with the SHT31-D and some supporting circuitry such as pullup resistors and capacitors, in the \u003ca href=\"\/en-eu\/collection\/stemma-qt\" target=\"_blank\"\u003eSTEMMA QT form factor\u003c\/a\u003e, making them easy to interface with.

This allows you to make solderless connections between your development board and the SHT31-D or to chain them with a wide range of other sensors and accessories using a compatible cable. \u003ca href=\"\/en-eu\/products\/jst-sh-cable-qwiic-stemma-qt-compatible\" target=\"_blank\"\u003eQT Cable is not included, but we have a variety in the shop.\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eEach 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.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-sht31-d-temperature-and-humidity-sensor-breakout\" target=\"_blank\"\u003eCheck out the tutorial for pinouts, assembly, wiring \u0026amp; tests, and more!\u003c\/a\u003e\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eUses I2C address 0x44 or 0x45\u003c\/li\u003e\n\u003cli\u003e12.7mm x 18mm x 2.6mm \/ 0.5\" x 0.7\" x 0.1\"\u003c\/li\u003e\n\u003cli\u003eWeight: 0.8g\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/adafruit-sht31-d-temperature-and-humidity-sensor-breakout\/downloads\" target=\"_blank\"\u003eDatasheet, schematic, EagleCAD PCB files, and Fritzing available in the product tutorial\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eRevision History\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of June 6, 2017\u003c\/strong\u003e we're using the version of the sensor with a PTFE filter.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of April 6, 2021\u003c\/strong\u003e Adafruit have 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!
