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 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 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.
