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 made up of a piezoresistive pressure sensor with a metal lid and gel encasing to protect the sensing elements from water and other environmental hazards.
Important to note that 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.
The SparkFun Qwiic Connect System is an ecosystem of I²C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector, reducing the amount of required PCB space. The polarized connections mean you can’t hook it up wrong.
Qwiic Micro is SparkFun's smallest I²C-supported board form-factor yet! At only 19.05mm by 7.62mm, Qwiic Micro is perfect for projects and applications that have space or weight concerns. With just a single Qwiic connector, Micro boards work great alongside the Qwiic Multiport or at the end of a Qwiic daisy chain.
Features of the SparkFun Qwiic LPS28DFW Micro Absolute Digital Barometer include a supply voltage range of 1.7 - 3.6V, current consumption of ~1.7 - 32.2µA in one shot mode and ~2.5 - 783.8µA in continuous mode, I²C interface (Qwiic-enabled), I²C addresses of 0x5C (Default) and 0x5D, water-resistant sensor package, dual pressure ranges of 260 - 1260hPa and 260 - 4060hPa, interrupt features including data-ready, FIFO flags, pressure threshold, output data rate range of 1 - 200Hz, and 1x Horizontal Qwiic Connection Port.
