The HDC302x is an integrated interface digital sensor that incorporates both humidity-sensing and temperature-sensing elements, an analog-to-digital converter, calibration memory, and an I2C compatible interface in a 2.50-mm × 2.50-mm, 8-pin WSON package. The HDC302x also provides excellent measurement accuracy at very low power.
The HDC302x measures relative humidity through variations in the capacitance of a polymer dielectric. As with most relative humidity sensors that include this type of technology, care must be taken to ensure optimal device performance for the sensing element. This includes:
