STMicroelectronics’ ultra-compact piezoresistive absolute pressure sensor functions as a digital output barometer
STMicroelectronics’ LPS27HHTW is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The device also embeds a temperature sensor to monitor ambient temperature. The LPS27HHTW comprises a sensing element and an IC interface that communicates through I²C, MIPI I3CSM, or SPI from the sensing element to the application.
