The HDC302x-Q1 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 2.50mm × 2.50mm, 8-pin WSON package. The HDC302x-Q1 also provides excellent measurement accuracy at very low power.
The HDC302x-Q1 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 provide optimal device performance. This includes:
Avoid exposure to outgassing substances and aggressive chemicals during PCB assembly and use. See HDC3x Silicon User's Guide for these guidelines.
