SHT40A-AW1B-R2

SHT40A-AW1B-R2 is a SHT4xA series 4th generation, high-accuracy, 16bit, automotive-grade relative humidity and temperature sensor. SHT4xA is an automotive-grade digital sensor platform for measuring relative humidity and temperature with different accuracy gradings. It fulfils demanding reliability requirements for automotive applications, such as 85°C/85%RH accelerated life tests. The sensors can be interfaced via I2C or pulse-width modulation. An integrated heater allows for advanced on-board diagnostics while the sensor element is designed for reliable operation in harsh conditions such as condensing environments. The four-pin dual-flat-no-leads package is suitable for surface mount technology (SMT) processing and can be ordered with a wettable flanks option.
