Description

The HTU21D-F is a small temperature and humidity sensor. Because It is so small, Adafruit has mounted it on this handy breakout board with all the additional components required to get it running. The sensor is ideal for environmental monitoring systems like weather stations or building HVAC.

Humidity and temperature measurements are very accurate across a fairly wide range with this sensor. Humidity ranges are ±2% through the optimized range of 5% to 95% relative humidity while temperature is accurate within ±1°C from -30°C to 90°C.

The sensor works with just about any microcontroller or single board computer out there as it both 3.3V and 5V logic compatible and uses a simple I2C interface. As always, Adafruit provides an excellent tutorial for this sensor and their easy to use Arduino library will have you up and running in no time! This sensor is STEMMA QT and Qwiic compatible – for fast and easy setup!
