                                                                                                  SHT41I digital, 4th generation, high-accuracy, 16bit, industrial-grade, relative humidity and temperature sensor. It 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. Patented protection options such as ePTFE membranes and polyimide foils can be pre-ordered. It is based on Sensirion’s proven CMOSens® Technology, which ensures the highest reliability. It features mature technology from global market leader, JEDEC JESD47 qualification, high ESD protection and patented protection options.
