STMicroelectronics LPS27HHTW
The LPS27HHTW is an ultra-compact piezoresistive absolute pressure sensor which 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 which communicates through I²C, MIPI I3CSM or SPI from the sensing element to the application.| Part No. | LPS27HHTW |
