    The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor.This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems.All you need is two lines for I2C communication and you’ll have relative humidity readingsand very accurate temperature readings as a bonus!
    There are only four pins that need to be hooked up in order to start using this sensor in a project.One for VCC, one for GND, and two data lines for I2C communication.This breakout board has built in 4.7k pull up resistors for I2C communications.If you’re hooking up multiple I2C devices on the same bus, you may want to disable these resistors.
    It's summer and you're sweating and your hair's all frizzy and all you really want toknow is why the weatherman said this morning that today's relative humidity would maxout at a perfectly reasonable 52% when it feels more like 77%.Enter the HTU21D-F Temperature + Humidity Sensor - the best way to prove the weatherman wrong!
    This I2C digital humidity sensor is an accurate and intelligent alternative to the much simplerHumidity and Temperature Sensor - SHT15 Breakout It has a typical accuracy of ±2% with anoperating range that's optimized from 5% to 95% RH. Operation outside this rangeis still possible - just the accuracy might drop a bit. The temperature output hasan 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. Such a lovely chip - so we spun up a breakout board that includes theFiltered 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 kindof microcontroller with 3.3V-5V power or logic. Each order comes with one fully assembledand tested PCB breakout and a small piece of header.You'll need to solder the header onto the PCB but it's fairly easy and takes only a few minutes even for a beginner. Board size:1.2x1cm(approx)
