3 Description
The HDC1008 is a digital humidity sensor with
integrated temperature sensor that provides excellent
measurement accuracy at very low power. The
device measures humidity based on a novel
capacitive sensor. The humidity and temperature
sensors are factory calibrated. The innovative
WLCSP (Wafer Level Chip Scale Package) simplifies
board design with the use of an ultra-compact
package. The sensing element of the HDC1008 is
placed on the bottom part of the device, which makes
the HDC1008 more robust against dirt, dust, and
other environmental contaminants. The HDC1008 is
functional within the full -40°C to +125°C temperature
range.
