The AHT20 is a nice but inexpensive temperature and humidity sensor from the same folks that brought Adafruit the DHT22. You can take sensor readings as often as you like, and it uses standard I2C so its super easy to use with any Arduino or Linux/Raspberry Pi board.
This sensor has a typical accuracy of +- 2% relative humidity, and +-0.3 °C at 20-80% RH and 20-60 °C. There is only one I2C address so it's not a good option when you need multiple humidity sensors.
As with all Adafruit breakouts, Adafruit have done the work to make this handy temperature-and-humidity super easy to use. Adafruit have put it on a breakout board with the required support circuitry and connectors to make it easy to work with and is now a trend Adafruit have added SparkFun Qwiic compatible STEMMA QT JST SH connectors that allow you to get going without needing to solder. Just use a STEMMA QT adapter cable, plug it into your favorite microcontroller or Blinka supported SBC and you're ready to rock! QT Cable is not included, but Adafruit have a variety in the shop.
