3 Description
The HDC1080 is a digital humidity sensor with
integrated temperature sensor that provides excellent
measurement accuracy at very low power. The
HDC1080 operates over a wide supply range, and is
a low cost, low power alternative to competitive
solutions in a wide range of common applications.
The humidity and temperature sensors are factory
calibrated.
