The STMicroelectronic LPS25HB is a compact and high-precision digital pressure sensor designed for accurate barometric measurements in portable and embedded systems. Built with a MEMS piezoresistive sensing element, it delivers reliable pressure readings from 260 to 1260 hPa with 24-bit resolution. The sensor integrates temperature compensation and factory calibration, ensuring stable performance across varying environmental conditions.
With ultra-low power consumption as low as 4 µA, it is ideal for battery-powered devices. The device supports both I²C and SPI interfaces for easy integration with microcontrollers. Its embedded FIFO buffer and interrupt features enhance system efficiency by reducing processor load. Packaged in a small HLGA-10 form factor, it is suitable for space-constrained applications like wearables, GPS systems, and weather monitoring devices.
