The digital SHTW1 humidity sensor is the result of Sensirion’s pursuit of consistent size reductions in our sensors. This chip-scale package humidity sensor is only one-seventh of the size of a comparable DFN humidity sensor and has a tiny footprint of 1. The SHTW1 humidity sensor is a digital humidity sensor in a wafer-level chip-scale package (WLCSP). This type of package opens up a new category of ultra-small humidity sensors, which are suitable for applications with the tightest space constraints.
