SparkFun Absolute Digital Barometer (LPS28DFW)

SparkFun Absolute Digital Barometer (LPS28DFW) features the STMicroelectronics LPS28DFW absolute barometer with a water-resistant package. The barometer is ideal for pressure measurement applications where the sensor is exposed to or submerged in water. The Qwiic system allows for integration into an I2C system, requiring no soldering. This Qwiic breakout also includes 0.1"-spaced PTH pins connected to the sensor's communication interface and interrupt pins for applications that require a traditional soldered connection.
