General Description

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 onpackage

patented PTFE [1] membrane or a removable protective cover. Sensor specific calibration

certificates according to ISO17025, identifiable through unique serial number, are available.
