General Description

SHT4xI-Digital is an industrial-grade digital sensor platform for measuring relative humidity and

temperature with different accuracy classes. It meets demanding ESD and robustness

requirements of industrial applications. The sensors can be interfaced via several preconfigured

I2C addresses. An integrated heater allows for advanced on-board-diagnostics while the sensor

element is designed for harsh conditions such as condensing environments. The four-pin dualflat-

no-leads package is suitable for surface mount technology (SMT) processing. Protection

options such as patented filter membranes and protective covers, available for any member of

the SHT4xI-Digital family, enable operation in harshest environments and advanced production

processes.
