Adafruit Sensirion SHT40 Temperature & Humidity Sensor - STEMMA QT / Qwiic(ada4885)

新版 Sensirion SHT40 溫度和濕度感應器 (ada4885)STEMMA QT / Qwiic

新版本STEMMA QT 影片(2021/2/3):https://youtu.be/bJdrzNyusgQ

What is STEMMA QT 影片說明 https://youtu.be/6GXRRuFuFy0

Description
 Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And finally, we have some that have a true I2C interface for easy reading. The SHT40 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT40 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C.
  Unlike some earlier SHT sensors, this sensor has a true I2C interface for easy interfacing with only two wires (plus power and ground!). Thanks to the voltage regulator and level shifting circuitry we've included on the breakout It is also is 3V or 5V compliant, so you can power and communicate with it using any microcontroller or microcomputer.
  Such a lovely chip - so we spun up a breakout board with the SHT4x and some supporting circuitry such as pullup resistors and capacitors. To make things even easier, we've included SparkFun Qwiic compatible STEMMA QT connectors for the I2C bus so you don't even need to solder! QT Cable is not included, but we have a variety in the shop
  If you prefer working on a breadboard, each order comes with one fully assembled and 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. 
  We've written both Arduino and CircuitPython/Python library code for this chip, so you can use it with just about any microcontroller or single-board computer like Raspberry Pi.
