SHT41-AD1B-R2

SHT41-AD1B-R2 is a SHT4x series 4th generation, high-accuracy, ultra-low-power, 16bit relative humidity and temperature sensor. SHT4x is a digital sensor platform for measuring relative humidity and temperature at different accuracy classes. Its I2C interface provides several preconfigured I2C addresses while maintaining an ultra-low power budget. The power-trimmed internal heater can be used at three heating levels thus enabling sensor operation in demanding environments. The four-pin dual-flat-no-leads package is suitable for surface mount technology (SMT) processing and comprises an optional on package patented PTFE [1] membrane or a removable protective cover.
