SHT31 in Sensirion SHT Temperature & Humidity Family
The SHT31 series by Sensirion represents a standard-performance sub-family of digital humidity and temperature sensors. Built on the proprietary CMOSens technology, these sensors integrate a capacitive humidity sensor and a bandgap temperature sensor on a single chip. Known for their reliability and long-term stability, they are widely used in environmental monitoring where high accuracy and digital integration are required. The family supports wide supply voltage ranges and offers multiple communication interfaces for versatile embedded integration.

Variants within the SHT31 family primarily differ by their output interface and packaging options. The DIS series utilizes a standard I2C digital protocol with programmable addresses, while the ARP series provides an analog ratiometric voltage output. Other differences include the quantity per reel, indicated by the 'kS' suffix, and the inclusion of protective filters or membranes to shield the sensor opening from water and dust ingress during assembly or operation.
