AF Sensirion SHT40 Temperature & Humidity Sensor

Very accurate temperature & humidity sensor with I2C interface, and Quiic / STEMMA QT connectors. The SHT40 has an excellent ±1.8% typical relative humidity accuracy from 25 to 75% and ±0.2 °C typical accuracy from 0 to 75 °C. 3.3V and 5V friendly. NIST traceability & JEDEC JESD47 qualification for sensor Arduino & CircuitPython libraries.

The typical read duration is 11 ms when set for SHT4X_HIGH_PRECISION with a M4 Express ATSAMD51 Cortex M4 microcontroller. Read duration drops to 3 ms when set for SHT4X_LOW_PRECISION.
