The Adafruit AHT20 Temperature & Humidity Sensor Breakout Board offers precise environmental measurements with a compact design. It utilizes the AHT20 sensor, providing a temperature accuracy of ±0.3°C and a humidity accuracy of ±2% RH. The sensor operates within a wide temperature range of -40°C to 85°C and a humidity range of 0% to 100%. Communication is facilitated via I²C with an address of 0x38, making it compatible with both 3.3V and 5V systems. The board features a STEMMA QT / Qwiic connector, enabling easy, solderless integration with platforms like Arduino and Raspberry Pi. Ideal for applications such as weather stations, HVAC systems, and indoor air quality monitoring.
