With selectable repeatability modes, programmable alert thresholds, two I2C addresses, and ultra-low 200nA standby current, it is designed for IoT environmental monitoring, HVAC, industrial process control, and smart home applications.","working_principle":"The SHT30-DIS-B2.5KS uses Sensirion's CMOSens technology, which integrates a capacitive humidity sensing element and a bandgap temperature sensor on a single CMOS chip alongside the signal conditioning and A\/D conversion circuitry. The capacitive humidity sensor measures relative humidity by detecting changes in the dielectric constant of a polymer layer as it absorbs or desorbs moisture. The bandgap temperature sensor provides a voltage proportional to absolute temperature. Both sensor outputs are digitized by a 16-bit ADC, then processed by the on-chip DSP which applies factory-calibrated linearization and temperature compensation coefficients stored in non-volatile memory. The corrected results are accessible via the I2C interface as 16-bit values for both humidity and temperature. Three repeatability modes trade measurement speed and noise: low (2.5ms, higher noise), medium (4.5ms), and high (12.5ms, lowest noise). The CRC-8 checksum appended to each data word ensures communication integrity. The alert mode can generate an interrupt when humidity or temperature crosses programmed thresholds without requiring I2C polling.","pin_description":"\n
