ILPS22QSTR

ILPS22QSTR is an absolute digital output barometer with embedded Qvar electrostatic sensor. This ultra-compact piezoresistive absolute pressure sensor which functions as a digital output barometer, supporting dual full-scale. It comprises a sensing element and an IC interface which communicates over I²C, MIPI I3CSM or SPI interfaces from the sensing element to the application and supports 1.2V digital interface as well. It embeds an analogue hub sensing functionality which is able to connect an analogue 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 leakage detection, tap, double tap, long press, and L/R - R/L swipe. Typical applications are industrial applications, gas and water metering, weather station equipment, altimeters and barometers for outdoor devices, smart filters, ventilators and CPAP equipment, man-down detection.
