SHT40I-BD1B-R3

SHT40I-BD1B-R3 is a SHT4xI-Digital 4th generation, high-accuracy, 16bit, industrial-grade, relative humidity and temperature sensor. 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 dual flat-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.
