Precision and Durability in Pressure Measurement: 7Semi LPS28DFW Mini Absolute Digital BarometerFor accurate, reliable, and water-resistant pressure measurements, choose the 7Semi LPS28DFW Mini Absolute Digital Barometer.
The 7Semi LPS28DFW Mini Absolute Digital Barometer is a high-performance barometric sensor that brings exceptional precision and reliability to a wide range of pressure measurement applications. Built around the STMicroelectronics LPS28DFW, this ultra-compact, piezoresistive pressure sensor stands out with its robust water-resistant package, making it ideal for environments where moisture exposure or submersion is common. With two full-scale measurement modes – 260 – 1260hPa and 260 – 4060hPa – this barometer delivers reliable absolute pressure readings with outstanding accuracy, making it perfect for various industrial, scientific, and environmental applications.
Designed with a traditional 0.1″-spaced PTH header and an I2C interface, the LPS28DFW seamlessly integrates into complex systems while maintaining low power consumption and reducing pressure noise. It also includes interrupt and ground pins, adding flexibility and control to your setup. Its durability is further ensured by a metal lid and gel protection, guarding sensitive components against environmental hazards.
