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.
