Adafruit HTU21D-F Temperature & Humidity Sensor

Product Description

The HTU21D-F Temperature + Humidity Sensor - the best way to accurately read both temperature and humidity. 

This I2C digital humidity sensor is an accurate and intelligent. It has a typical accuracy of ±2% with an operating range that's optimized from 5% to 95% RH. Operation outside this range is still possible - just the accuracy might drop a bit. The temperature output has an accuracy of ±1°C from -30~90°C. 

Such a lovely chip - so we spun up a breakout board that includes the Filtered version (the white bit of plastic which is a PTFE filter to keep the sensor clean), a 3.3V regulator and I2C level shifting circuitry. This lets you use it safely with any kind of microcontroller with 3.3V-5V power or logic.
