SENSIRION SHT40-AD1F-R2 Humidity and Temperature Sensor, PTFE Membrane, Digital, 0% to 100% Relative Humidity, I2C, DFN-4

SHT40-AD1F-R2 is a SHT4x 4th Gen. relative humidity and temperature sensor. Its I2C interface provides several preconfigured I2C addresses while maintaining an ultra-low power budget (0.4?W). 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 protective cover. Its suitability for standard SMD assembly processes makes the SHT4x series ideal for high-volume applications. It builds on a completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications.
