Enter the \u003cstrong\u003eHTU21D-F Temperature + Humidity Sensor\u003c\/strong\u003e - the best way to prove the weatherman wrong!\u003cbr\u003e\u003cbr\u003eThis I2C digital humidity sensor is an accurate and intelligent alternative to the much simpler Humidity and Temperature Sensor - SHT15 Breakout 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. If you're looking to measure temperature more accurately, we recommend the MCP9808 High Accuracy I2C Temperature Sensor Breakout Board.\u003cbr\u003e\u003cbr\u003eSuch 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. \u003cstrong\u003eEach order comes with one fully assembled and tested PCB breakout with headers attached and everything.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eIt's also very easy to use, thanks to our Arduino library and tutorial.
