Pressure Sensor 4.35PSI ~ 18.13PSI (30kPa ~ 125kPa) Absolute 10-WFLGA
The BMP581 is a high-precision digital barometric pressure sensor designed for altitude tracking, environmental monitoring, navigation, weather sensing, and industrial measurement applications. It integrates a MEMS pressure sensing element with a low-noise analog front end and digital signal processing to deliver highly accurate pressure and temperature measurements over a wide operating range. The device supports low-power operation, making it suitable for portable, battery-powered, and always-on sensing systems.
The sensor communicates through standard digital interfaces and includes configurable sampling, filtering, and interrupt features for flexible system integration. Its compact package enables use in space-constrained embedded designs such as wearables, mobile devices, drones, smart home systems, IoT devices, and industrial instrumentation.
