Product Summary

SHT3x-DIS is the next generation of Sensirion’s

temperature and humidity sensors. It builds on a new

CMOSens® sensor chip that is at the heart of

Sensirion’s new humidity and temperature platform.

The SHT3x-DIS has increased intelligence, reliability

and improved accuracy specifications compared to its

predecessor. Its functionality includes enhanced signal

processing, two distinctive and user selectable I2C

addresses and communication speeds of up to 1 MHz.

while keeping a height of 0.9 mm. This allows for

integration of the SHT3x-DIS into a great variety of

applications. Additionally, the wide supply voltage range

of 2.4 V to 5.5 V guarantees compatibility with diverse

assembly situations. All in all, the

SHT3x-DIS

incorporates 15 years of knowledge of Sensirion, the

leader

in

the

humidity

sensor

industry.



High reliability and long-term stability



Industry-proven technology with a track record of

more than 15 years



Designed for mass production



High process capability



High signal-to-noise ratio
