The SparkFun Qwiic AHT20 is a compact humidity and temperature sensor breakout built around the ASAIR AHT20 sensor. It delivers high-accuracy measurements — temperature within ±0.3 °C and relative humidity within ±2% — at a low price point.

The board connects via the Qwiic (I²C) connector system for solderless, plug-and-play integration. No voltage regulation or level shifting is required. A SparkFun Arduino library is available for easy reading of temperature and humidity data.
