Adafruit AHT20 - Temperature & Humidity Sensor Breakout Board

The AHT20 temperature and humidity sensor is an affordable yet powerful component designed for seamless integration into your projects. It employs standard I2C communication, ensuring straightforward compatibility with Arduino and Linux/Raspberry Pi boards.

With an accuracy of ±2% for relative humidity and ±0.3 °C within the 20-80% RH and 20-60 °C range, it delivers reliable readings. Measuring temperature and humidity as frequently as needed is made easy with this sensor. It's important to note that it supports only a single I2C address, which limits its use when multiple sensors are required.

Adafruit provides the breakout board with essential support circuitry and connectors, featuring STEMMA QT JST SH connections. This setup eliminates the need for soldering. Simply connect it with a STEMMA QT adapter cable to your microcontroller or Blinka-supported SBC, and you're good to go. Please note, the QT Cable is not included, but a variety are available separately.
