Overview

The Grove 101020492 is a high-performance 3-axis digital magnetometer based on the Bosch BMM150 sensor. It provides precise compass headings and magnetic field detection for mobile and stationary applications, supporting both I2C and SPI interfaces via the Grove ecosystem. The board operates within a voltage range of 3.3V to 5V and features a wide measurement range of +/-1300uT for the X/Y axes and +/-2500uT for the Z axis.

Why Choose This Part

The BMM150 sensor offers low power consumption and high sensitivity, making it ideal for battery-operated devices. Integration is simplified through the Grove plug-and-play connector, eliminating the need for soldering or manual level shifting when used with compatible base shields.

Applications

Electronic Compasses
Used in navigation systems to determine heading relative to the Earth magnetic field.
UAV and Robotic Navigation
Provides orientation and tilt-compensated heading data for drones and mobile robots.
Magnetic Field Detection
Sensing proximity or changes in local magnetic environments for industrial or security applications.
