The SHT41A-FD1B-R2 is a high-reliability digital sensor platform designed for automotive applications. It offers a pulse-width modulation (PWM) interface and is built on Sensirion's CMOSens technology. The sensor is AEC-Q100 qualified and features a power heater for self-diagnosis and creep mitigation. It is designed to withstand harsh environments, including 85°C/85%RH accelerated life tests, and includes wettable flanks for automated optical inspection.
