Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. And finally, Adafruit have some that have a true I2C interface for easy reading. The SHT45 sensor is the fourth generation (started at the SHT10 and worked its way up to the top!). The SHT45 has an excellent ±1.0% typical relative humidity accuracy from 25 to 75% and ±0.1°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 Adafruit have 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 they spun up a breakout board with the SHT45 and some supporting circuitry such as pullup resistors and capacitors. To make things even easier, Adafruit have 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 Adafruit 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.
