SHT40A in Sensirion SHT Temperature & Humidity Family
The SHT40A family represents Sensirion's fourth-generation digital humidity and temperature sensors specifically optimized for automotive environments. These sensors are built on an enhanced CMOSens technology platform, providing high reliability and precision in a compact 4-pin dual-flat no-lead (DFN) package. Designed for mass-market automotive integration, the SHT40A offers AEC-Q100 qualification and a wide supply voltage range, making it a standard choice for climate control systems and powertrain monitoring where space and durability are critical requirements.
Variants in This Sub-Family
Variants within the SHT40A sub-family are primarily distinguished by their specific I2C address configurations and the presence of protective membranes. Most members utilize the standard I2C interface but offer different hard-coded addresses to allow multiple sensors on a single bus. Additionally, certain part numbers include an integrated filter membrane or protective cover to shield the sensing element from dust, water ingress, and chemical contaminants during harsh automotive assembly or operation.
