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.
