Sensirion SHT41A Automotive Humidity & Temperature Sensors

Sensirion SHT41A Automotive Humidity and Temperature Sensors offer a 2.3V to 5.5V supply voltage range, AEC-Q100 qualification, and relative humidity accuracy of up to ±2%RH. The SHT41A series is a digital sensor platform designed to measure relative humidity and temperature with different accuracy gradings. These sensors can interface via I2C or pulse-width modulation and feature an integrated heater that allows for advanced onboard diagnostics, while the sensor element is designed for reliable operation in harsh conditions. Sensirion SHT41A Sensors has a four-pin, dual-flat-no-leads package for SMT processing and is suitable for automotive applications.
