About this item

The HTU21D-F Temperature & Humidity Sensor Breakout Board from Adafruit is a compact and precise I²C-based sensor module designed for accurate environmental monitoring. It offers a typical relative humidity accuracy of ±2% within the 5% to 95% RH range and a temperature accuracy of ±1°C from -30°C to 90°C. The board operates on a 3.3V to 5V supply and includes onboard I²C level shifting circuitry, making it compatible with various microcontrollers. Its small form factor (18mm x 16mm) and low power consumption (approximately 1.4g weight) make it ideal for applications like weather stations, HVAC systems, and IoT devices.
