It sets the industry standard in humidity sensing by combining multiple functions and various interfaces (I2C, analog voltage output) with a wide operating voltage range of 2.15 to 5.5V. The SHT3x series consists of the SHT30 (low-cost), SHT31 (standard), and SHT35 (high-end) variants. The SHT31-DIS-B2.5KS is the standard version with \u00b12% RH accuracy. Built on Sensirion's CMOSens technology, the sensor integrates a capacitive humidity sensor, a bandgap temperature sensor, signal processing, and calibration data on a single chip. The DFN package measures just 2.5 x 2.5 x 0.9 mm, making it ideal for space-constrained applications.","working_principle":"The SHT31-DIS-B2.5KS operates through three key subsystems:\n\n1. Sensing Elements: A capacitive humidity sensor and a bandgap temperature sensor are co-located on the CMOSens chip. The humidity sensor uses a polymer dielectric whose capacitance changes with moisture absorption. The temperature sensor utilizes a bandgap reference circuit for precise temperature measurement.\n\n2. Signal Processing: An integrated ADC converts the analog signals from both sensing elements into 16-bit digital values. The sensor applies linearization and compensation for temperature and supply voltage effects internally, outputting fully calibrated data.\n\n3. I2C Communication: The sensor communicates via a standard I2C interface at clock frequencies up to 1 MHz. Two I2C addresses (0x44 and 0x45) are selectable via the ADDR pin. Each measurement transaction includes an 8-bit CRC checksum (polynomial 0x31) for data integrity. The sensor supports single-shot and periodic measurement modes with configurable repeatability (low, medium, high).","pin_description":"
