The Crowtail HTU21D module integrates the Sensirion HTU21D(F) sensor IC, a calibrated digital sensor renowned for its high accuracy and long-term stability. It measures relative humidity with a typical accuracy of ±2% RH and temperature with a typical accuracy of ±0.3°C. The sensor communicates via a standard I2C interface, outputting fully calibrated digital signals.
The module includes an onboard AMS1117 voltage regulator, allowing it to be safely powered from a 5V source while providing the 3.3V required by the HTU21D sensor chip. This design ensures compatibility with common 5V development boards like Arduino Uno and Crowduino, while also supporting native 3.3V logic systems. Its compact Crowtail form-factor allows for quick connection to compatible base shields without soldering.
