3 Description

The HDC3120 is an integrated, capacitive based

relative humidity (RH) and temperature sensor

where the relative humidity and temperature sensor

results are represented as ratiometric analog output.

Conversion of signals to the analog domain provides

a robust design for applications requiring signal

transmission over wire or other distance-based

use cases. The device provides high accuracy

measurements over a wide supply range (1.62V –

5.5V) and low power consumption while maintaining

less than 0.19% long term drift per year. The

HDC3120 is available in a compact 2.5mm × 2.5mm

× 0.8mm WSON 8-pin package. Both the temperature

and humidity sensors are 100% tested and calibrated

on a production setup that is NIST traceable and

verified with equipment that is calibrated to ISO/IEC

17025 standards.
