HTU21 - Digital Relative Humidity sensor

Download the HTU21 datasheet PDF. This datasheet also covers the HTU21D variant, as both devices belong to the same digital relative humidity sensor family and are provided as variant models within a single manufacturer datasheet.

General Description

The HTU21D(F) is a new digital humidity sensor with temperature output by MEAS.

Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm footprint.

HTU21D(F) Sensor Digital Relative Humidity sensor with Temperature output  DFN type package  Relative Humidity and Temperature Digital Output, I²C interface  Fully calibrated  Lead free sensor, reflow solderable  Low power consumption  Fast response time DESCRIPTION The HTU21D(F) is a new digital humidity sensor with temperature output by MEAS. Setting new standards in terms of size and intelligence, it is embedded in a reflow solderable Dual Flat No leads (DFN) package with a small 3 x 3 x 0.9 mm footprint. This sensor provides calibrated, linearized signals in digital, I²C format. HTU21D(F) digital humidity sensors are dedicated humidity and temperature plug and play transducers for OEM applications where reliable and accurate measurements are needed.
