3 Description

The HDC3120-Q1 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 solution in 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-Q1 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.
