Overview

The LPS25HBTR is a compact piezoresistive absolute pressure sensor that functions as a digital output barometer. It features a wide measurement range of 260 to 1260 hPa and integrates temperature compensation to ensure stable readings across varying environmental conditions.

Why Choose This Part

This sensor offers an extremely low current consumption of 4.5 microamps in low-noise mode and features a 20x full-scale overpressure capability. Its embedded FIFO and interrupt functions for data-ready and pressure thresholds help reduce the host processor workload.

Applications

Altimeter and Barometer
High-resolution 24-bit output allows for precise altitude calculation in handheld devices and weather stations.
Enhanced GPS Navigation
Provides dead-reckoning support and floor detection for indoor positioning systems by sensing minute pressure changes.
Industrial Instrumentation
Suitable for board-mount pressure monitoring in equipment requiring high shock survivability up to 10,000 g.
