Sensirion Temperature/Humidity sensors are some of the finest & highest-accuracy devices you can get. The SHT41 sensor is the fourth generation of I2C temperature and humidity sensor from Sensirion. (They started at the SHT10 and worked its way up to the top!). The SHT41 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C.
Note that compared to the SHT40, the SHT41 has the same typical accuracy of ±1.8% RH from 25-75% but has much better accuracy over the full humidity range, with a typical accuracy of ±2% over the 0-100% RH range, whereas the SHT40 has a worst-case typical accuracy of ±3%. Also, the SHT41 max accuracy is ±3% where as the SHT40 has a max accuracy of ±6%. So basically, you'll get better accuracy for not-much-more cost. If you need the 'best' of the SHT4x series, check out the SHT45
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 SHT41 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.
Adafruit have 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.
