Like the HTU21, the '31\nis great for sensing temperature and humidity, with excellent specifications.\nThis I2C digital humidity sensor is an accurate and intelligent alternative to\nthe common DHT-series sensors, at about the same price! It has a typical\naccuracy of ±2% at 20% to 100% relative humidity, at a temperature range of 0\nto 70°C. Operation outside this range is still possible - just the accuracy\nmight drop a bit. The temperature output has an accuracy of ±0.2°C from\n-0~100°C, on par with the better quality on-chip sensors we've stocked. The\nsensor also has an on-board heater that can be controlled on and off to help\nevaporate condensation on the sensing element. Of course, temperature sensing\nwill not be accurate with the heater on. Data reads come with CRC, so you can\nbe more confident of data that is read compared to other I2C sensors. Other\nnice extras: a hardware reset pin, an address-select pin so you can have two\non one I2C bus, and a thermal-isolation cut out so nearby circuitry has less\neffect on the readings. To get you going fast, we spun up a custom made PCB in\nthe STEMMA QT form factor, making them easy to interface with. The STEMMA QT\nconnectors on either side are compatible with the SparkFun Qwiic I2C\nconnectors. This allows you to make solderless connections between your\ndevelopment board and the HTU31Ds or to chain them with a wide range of other\nsensors and accessories using a compatible cable. QT Cable is not included,\nbut we have a variety in the shop. You can use this sensor safely with any\nkind of microcontroller\/microcomputer with 3.3V-5V power or logic. Each order\ncomes with one fully assembled and tested PCB breakout and a small piece of\nheader. You'll need to solder the header onto the PCB to use in a breadboard\nbut it's fairly easy and takes only a few minutes even for a beginner.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n \u003cul class=\"a\"\u003e\n \u003cli\u003ehas an on-board heate\u003c\/li\u003e\n \u003cli\u003ehardware reset pin\u003c\/li\u003e\n \u003cli\u003ethermal-isolation cut out\u003c\/li\u003e\n \u003c\/ul\u003e","published_at":"2026-09-03T00:23:00+10:00","created_at":"2026-09-02T20:33:45+10:00","vendor":"Adafruit","type":"Temperature Probes \u0026 Sensors","tags":["industrial_UK_Aug2026"],"price":16700,"price_min":16700,"price_max":16700,"available":true,"price_varies":false,"compare_at_price":null,"compare_at_price_min":0,"compare_at_price_max":0,"compare_at_price_varies":false,"variants":[{"id":44375802183860,"title":"Default Title","option1":"Default Title","option2":null,"option3":null,"sku":"uk-B09G3JBHDG","requires_shipping":true,"taxable":true,"featured_image":null,"available":true,"name":"Adafruit HTU31 Temperature \u0026 Humidity Sensor Breakout Board - Stemma QT\/Qwiic 4832","public_title":null,"options":["Default Title"],"price":16700,"weight":9,"compare_at_price":null,"inventory_management":"shopify","barcode":"4832","requires_selling_plan":false,"selling_plan_allocations":[],"quantity_rule":{"min":1,"max":null,"increment":1}}],"images":["\/\/auspowers.com\/cdn\/shop\/files\/uk-B09G3JBHDG.jpg?v=1788345227","\/\/auspowers.com\/cdn\/shop\/files\/41FjGNM0dhL.jpg?v=1788345227","\/\/auspowers.com\/cdn\/shop\/files\/51L0H6LzpnL.jpg?v=1788345228","\/\/auspowers.com\/cdn\/shop\/files\/51SWyn2mCTL.jpg?v=1788345228","\/\/auspowers.com\/cdn\/shop\/files\/419BxGbLxLL.jpg?v=1788345228","\/\/auspowers.com\/cdn\/shop\/files\/51YkOg2lUKL.jpg?v=1788345228","\/\/auspowers.com\/cdn\/shop\/files\/51QOt-JfDzL.jpg?v=1788345228"],"featured_image":"\/\/auspowers.com\/cdn\/shop\/files\/uk-B09G3JBHDG.jpg?v=1788345227","options":["Title"],"media":[{"alt":null,"id":33276864790708,"position":1,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/uk-B09G3JBHDG.jpg?v=1788345227"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/uk-B09G3JBHDG.jpg?v=1788345227","width":500},{"alt":null,"id":33276864823476,"position":2,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/41FjGNM0dhL.jpg?v=1788345227"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/41FjGNM0dhL.jpg?v=1788345227","width":500},{"alt":null,"id":33276864856244,"position":3,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51L0H6LzpnL.jpg?v=1788345228"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51L0H6LzpnL.jpg?v=1788345228","width":500},{"alt":null,"id":33276864889012,"position":4,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51SWyn2mCTL.jpg?v=1788345228"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51SWyn2mCTL.jpg?v=1788345228","width":500},{"alt":null,"id":33276864921780,"position":5,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/419BxGbLxLL.jpg?v=1788345228"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/419BxGbLxLL.jpg?v=1788345228","width":500},{"alt":null,"id":33276864954548,"position":6,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51YkOg2lUKL.jpg?v=1788345228"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51YkOg2lUKL.jpg?v=1788345228","width":500},{"alt":null,"id":33276864987316,"position":7,"preview_image":{"aspect_ratio":1.333,"height":375,"width":500,"src":"\/\/auspowers.com\/cdn\/shop\/files\/51QOt-JfDzL.jpg?v=1788345228"},"aspect_ratio":1.333,"height":375,"media_type":"image","src":"\/\/auspowers.com\/cdn\/shop\/files\/51QOt-JfDzL.jpg?v=1788345228","width":500}],"requires_selling_plan":false,"selling_plan_groups":[],"content":"\u003ch3\u003eAdafruit HTU31 Temperature \u0026amp; Humidity Sensor Breakout Board - Stemma QT\/Qwiic 4832\u003c\/h3\u003e\n\u003cp id=\"b\"\u003eThe HTU31-D is the third generation of temperature-humidity sensors from TE -\nand a great follow-up to the popular HTU21-D sensor.
