HDC2022 Datasheet Low-power Humidity And Temperature Sensor

Manufacturer: Texas Instruments

Overview: .ti. HDC2022 SNAS774A – DECEMBER 2019 – REVISEDHJDUNCE22002220 SNAS774A – DECEMBER 2019 – REVISED JUNE 2020 HDC2022 High-Accuracy, Low-Power Humidity and Temperature Sensor With IP67 Rated Water and Dust Protection.

General Description

The HDC2022 is an integrated relative humidity and temperature sensor with a factory-installed PTFE membrane cover over the opening of the relative humidity sensor.

The cover is a hydrophobic micropourous PTFE foil that protects against dust and water according to IP67 specifications.

The cover is designed to adhere to the package over lifetime operation while maintaining the same response time as a sensor without the membrane.
