| Market Reality | The Sensirion SHT family is the reference humidity sensor of HVAC, medical devices, weather stations and every environmental logger: four generations of the same promise - a factory-calibrated digital RH/temperature pair on I2C - with the accuracy ladder running from the SHT21 baseline to the SHT45 top grade. Across the generations nothing physical carried over: the SHT3x lives in a 2.5mm DFN-8 with an address pin and a 5V-tolerant supply, while the SHT4x generation shrank to a 1.5mm DFN-4, dropped the supply ceiling to 3.6V, fixed the address at order time and removed clock stretching. The market demand spike on the 4x generation made this page necessary: substitutions happen constantly and every one of them crosses at least one of those lines. | The Sensirion SHT family is the reference humidity sensor of HVAC, medical devices, weather stations and every environmental logger: four generations of the same promise - a factory-calibrated digital RH/temperature pair on I2C - with the accuracy ladder running from the SHT21 baseline to the SHT45 top grade.
