LPS27HHTW MEMS Pressure Sensor STMicroelectronics LPS27HHTW MEMS Pressure Sensor is an ultra-compact piezoresistive absolute pressure sensor that functions as a digital output barometer. The LPS27HHTW Sensor also embeds a temperature sensor to monitor the ambient temperature. The LPS27HHTW includes a sensing element and an IC interface that communicates through I2C, MIPI I3CSM, or SPI from the sensing element to the application. The sensing element detects absolute pressure and consists of a suspended membrane manufactured using a dedicated process developed by ST.
