The device comprises a sensing element and an IC interface that communicates over the I²C or MIPI I3CSM interface from the sensing element to the application. The ILPS28QSW provides lower power consumption, achieving lower pressure noise than its predecessor. The ILPS28QSW embeds an analog hub sensing functionality that is able to connect an analog input and convert it to a digital signal for embedded processing. In addition, an embedded Qvar (electric charge variation detection) channel can be enabled for sensing in applications such as water-leak detection, tap, double tap, long press, and L/R - R/L swipe.
