 10% to 90% ratiometric analog voltage output
 Typical accuracy of  2%RH and  0.3°C
 Parallel measurement of temperature and humidity
at separate pins
 Tiny 8-Pin DFN package
Product Summary
SHT3x-ARP 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-
ARP has increased intelligence, reliability and improved
accuracy specifications compared to its predecessor. Its
functionality includes enhanced signal processing,
temperature and humidity can be read out at different
pins. 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-ARP 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-ARP
incorporates 15 years of knowledge of Sensirion, the
leader in the humidity sensor industry.
