Overview

The SEN0251 is a high-performance barometric pressure sensor module based on the Bosch BMP388, integrated into the DFRobot Gravity ecosystem. It offers a wide measurement range from 300 to 1250 hPa with exceptional temperature stability and low noise, making it suitable for precise altitude and environmental monitoring. The module includes a Gravity connector for easy plug-and-play integration with 3.3V and 5V microcontrollers.

Why Choose This Part

The module features a best-in-class offset temperature coefficient, ensuring accurate readings even as environmental temperatures fluctuate between -40C and 80C. Its Gravity-compatible design includes an onboard voltage regulator supporting a wide input range of 3.3V to 5.5V, while maintaining a low run current of 0.5mA.

Applications

Drone Altitude Hold
Provides high-resolution pressure data for precise vertical positioning and stability in UAVs.
Indoor Navigation
Enables floor-level detection and 3D positioning inside buildings where GPS signal is unavailable.
Portable Weather Stations
Measures local atmospheric pressure and temperature with low power consumption for battery-operated devices.
GPS Enhancement
Reduces time-to-first-fix and improves vertical accuracy in navigation systems by providing reliable altitude offsets.
