{"product_id":"adafruit-htu31-temperature-humidity-sensor-breakout-board-stemma-qt-qwiic","title":"Adafruit HTU31 Temperature \u0026 Humidity Sensor Breakout Board","description":"\u003cp\u003eThe HTU31-D is the third generation of temperature-humidity sensors from TE - and \u003ca href=\"\/en-eu\/products\/adafruit-htu21d-f-temperature-humidity-sensor-breakout-board\" target=\"_blank\"\u003ea great follow-up to the popular HTU21-D sensor\u003c\/a\u003e. Like the HTU21, the '31 is great for sensing temperature and humidity, with excellent specifications.\u003c\/p\u003e\n\u003cp\u003eThis I2C digital humidity sensor is an accurate and intelligent alternative to the common DHT-series sensors, at about the same price! It has a typical accuracy of ±2% at 20% to 100% relative humidity, at a temperature range of 0 to 70°C. Operation outside this range is still possible - just the accuracy might drop a bit. The temperature output has an accuracy of ±0.2°C from -0~100°C, on par with the better quality on-chip sensors we've stocked.\u003c\/p\u003e\n\u003cp\u003eThe sensor also has an on-board heater that can be controlled on and off to help evaporate condensation on the sensing element. Of course, temperature sensing will not be accurate with the heater on. Data reads come with CRC, so you can be more confident of data that is read compared to other I2C sensors.\u003c\/p\u003e\n\u003cp\u003eOther nice extras: a hardware reset pin, an address-select pin so you can have two on one I2C bus, and a thermal-isolation cut out so nearby circuitry has less effect on the readings.\u003c\/p\u003e\n\u003cp\u003eTo get you going fast, Adafruit spun up a custom made PCB in the \u003ca href=\"\/en-eu\/collections\/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 HTU31Ds 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 You can use this sensor safely with any kind of microcontroller\/microcomputer with 3.3V-5V power or logic.\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 in a breadboard but it's fairly easy and takes only a few minutes even for a beginner.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003eUses I2C address 0x40 or 0x41\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of December 2, 2022\u003c\/strong\u003e – Adafruit have updated this PCB with \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_Pinguin\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eAdafruit Pinguin\u003c\/a\u003e to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
