DESCRIPTION
The HTU31-D is the third generation of temperature-humidity sensors and like the HTU21, the ’31 is great for sensing temperature and humidity, with excellent specifications.
This 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.
The sensor also has an onboard 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 about the data that is read compared to other I2C sensors.
Other nice extras: hardware reset pin, an address-select pin so you can have two on one I2C bus, and thermal isolation cut out so nearby circuitry has less effect on the readings.
To get you going fast, it has a custom made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. 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 (QT Cable is not included.) You can use this sensor safely with any kind of microcontroller/microcomputer with 3.3V-5V power or logic
