SHT43
Digital humidity sensor with ISO17025 certification
The SHT4x is a digital sensor platform that enables relative humidity and temperature measurements with market-leading performance. This sensor family offers reduced power consumption and its exceptionally small size in a robust DFN housing enables it to be integrated into challenging designs while catering to the highest reliability demands. In particular, every SHT43 exhibits a best-in-class drift of <0.01 °C per year and comes with a unique ISO17025 three-point temperature calibration certificate, which enables cost-effective, high-volume manufacturing e.g. of GDP compliant dataloggers. Calibration certificates and data for full reels and each individual SHT43 can be downloaded from libellus.sensirion.com.
