3 Description

The HDC1000 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 HDC1000 is

placed on the bottom part of the device, which makes

the HDC1000 more robust against dirt, dust, and

other environmental contaminants. The HDC1000 is

functional within the full -40°C to +125°C temperature

range.
