ILPS28QSW Dual Absolute Digital Output Barometer STMicroelectronics ILPS28QSW Dual Absolute Digital Output Barometer is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device features a dual full-scale up to user selectable 4060hPa. The device incorporates a sensing element and an IC interface communicating over the I2C or MIPI I3CSM interface from the sensing element to the application. The ILPS28QSW delivers lower power consumption, achieving lower pressure noise than its predecessor.
