Product Specification

SHT31-ARP Analog Voltage Output Humidity and Temperature Sensor 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 mm2 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.
