The SmartElex BMM150 3 Axis Magnetometer Sensor is a compact digital sensor designed to measure magnetic fields along three axes. It helps users accurately detect orientation and heading, making it useful in projects where direction sensing and magnetic field measurement are required. This sensor is suitable for students, makers, engineers, educators, and startups working on embedded systems, learning projects, and prototype development that need reliable magnetic sensing in a small and easy-to-use form.
This 3 axis magnetometer sensor is commonly used in robotics, IoT devices, navigation systems, and automation projects that require compass functionality or motion awareness. It can be easily integrated with popular development platforms such as Arduino, Raspberry Pi, and ESP32, allowing smooth data communication and quick setup. The stable performance and simple interfacing make it ideal for applications like robot navigation, electronic compasses, orientation tracking, and smart sensor-based systems
Note - The default configuration of module is I2C interface, for SPI interface remove I2C smd jumper & short SPI smd jumper on module.
