Adafruit HTS221 - Temperature & Humidity Sensor Breakout Board - STEMMA QT / Qwiic

The HTS221 can measure relative humidity from 0%-100% rH with a sensitivity of 0.004% and 3.5% accuracy between 20-80%. It can also measure temperature from -40 to 120 degrees C, with a resolution of 0.016 C with +-0.5 C accuracy between 15 and +40 C. The HTS221 is an inexpensive humidity sensor which makes it great for everyday measurement applications.

The HTS221 lets you choose between a 3-wire SPI or the ever-popular I2C which only needs two wires for data. It's easy to use on a breadboard with either a 5V logic level device like a Metro 328 or Arduino Uno, or with 3.3V logic level devices like a Feather M4 or Raspberry Pi of your choice.
