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 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 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.
