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.
The DFN package has a footprint of 2.5 x 2.5 mm
2
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.
