STMicroelectronics LPS27DEWO Pressure Sensor
STMicroelectronics LPS27DEWO Pressure Sensor is an ultracompact piezoresistive absolute pressure sensor that functions as a digital output barometer. This sensor offers low power consumption and lower pressure noise than its predecessor. The LPS27DEWO sensor comprises a sensing element and a digital interface that communicates with the application over I²C, MIPI I3C®, or SPI. This sensor operates over a temperature range extending from -40°C to +85°C. The LPS27DEWO sensor is available in an LGA package with a metal lid. This package is designed to allow external pressure to reach the sensing element. The LPS27DEWO sensor is ideal for wearables, altimeters and barometers for portable devices, GPS applications, weather station equipment, sport watches, e-cigarettes, and water depth monitoring.
