In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT40 offers the best price-performance ratio on the market. Tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT4x ideal for high-volume applications.

The SHT40 builds on a completely new and optimized CMOSens® chip that offers reduced power consumption and improved accuracy specifications. With the extended supply voltage range from 1.08 V to 3.6 V, it’s the perfect fit for mobile and battery-driven applications. The exceptionally small size in a robust DFN housing enables integration into challenging designs while meeting the highest reliability demands, as demonstrated by the JEDEC JESD47 qualification.
