SHT41

  • All products
  • •Humidity sensors
  • •SHT4x

±1.8% / max. ±2.5% RH Digital humidity and temperature sensor

In line with Sensirion’s industry-proven humidity and temperature sensors, the SHT41 offers the best price-performance ratio on the market. Tape and reel packaging combined with its suitability for standard SMD assembly processes make the SHT41 ideal for high-volume applications. 

 

The SHT41 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. On top of that, the SHT41 is compliant with the relevant healthy building standards RESET® and WELL Building Standard™.
