5X(HTU21D Temperature & Humidity Sensor Breakout Board Module C6M9)
5X(The HTU21D is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. This sensor is Perfect 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 readings and 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 to know is why the weatherman said this morning that today`s relative humidity would max out 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!
Color: blue
Material: plastic
This 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 Celsius from -30~90 Celsius . 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 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. Each order comes with one fully assembled )
