HTU21D datasheet



This is Digital Relative Humidity sensor with Temperature output.

The HTU21D 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.

Direct interface with a micro-controller is made possible with the module for humidity and temperature digital outputs. These low power sensors are designed for high volume and cost sensitive applications with tight space constraints.

Ordering Informations :



1. Full interchangeability with no calibration required in standard conditions

2.  Instantaneous desaturation after long periods in saturation phase

3.  Compatible with automatized assembly processes, including Pb free and reflow processes

4. Individual marking for compliance to stringent traceability requirements
