The Sensirion's humidity and temperature sensor IC used for measuring relative humidity and temperature at different accuracy classes. Its I2C interface provides several preconfigured I2C addresses and maintains 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 membrane or a removable protection cap.
