HDC3021 Datasheet Digital Relative Humidity Sensor

Manufacturer: Texas Instruments

Overview: HDC3020, HDC3021, HDC3022 SNAS778C – JUNE 2021 – REVISED DECEMBER 2022 HDC302x 0.5%RH Digital Relative Humidity Sensor, 0.19%RH/yr Long Term Drift, 4s Response, Low-Power, Offset Error Correction, 0.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The HDC302x is an integrated capacitive based relative humidity (RH) and temperature sensor.

It provides high accuracy measurements over a wide supply range (1.62 V – 5.5 V), along with ultra-low power consumption in a pact 2.5-mm × 2.5-mm package.

Both the temperature and humidity sensors are 100% tested and trimmed on a production setup that is NIST traceable and verified with equipment that is calibrated to ISO/IEC 17025 standards.
