The SparkFun Qwiic LPS28DFW Absolute Digital Barometer offers a unique barometer breakout featuring the LPS28DFW from STMicroelectronics©. The LPS28DFW is an absolute barometer with a water-resistant package making it perfect for pressure measurement applications where the sensor is exposed to or even submerged in water. The Qwiic system allows for integration into your I2C system with no soldering required. 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.
The sensor has two full-scale measurement ranges of 260 - 1260hPa and 260 - 4060hPa with an absolute pressure accuracy of 0.5hPa. The LPS28DFW is composed of a piezoresistive pressure sensor with a metal lid and gel encasing to protect the sensing elements from water and other environmental hazards.
Important! While the LPS28DFW is protected from water, the rest of the components on these breakouts are not protected by any conformal coating and can be damaged by exposure to liquids. Users who intend to use these breakouts in applications where the board may be exposed to water or other liquids should apply a conformal coating to the board or place it in a sealed container prior to use.
