BMM150 Magnetometer

Description :

The BMM150 is a compact, low-power, and high-performance 3-axis digital magnetometer developed by Bosch Sensortec. It is designed to measure the Earth's magnetic field with high accuracy and is often used in applications such as navigation, augmented reality, gaming, and other scenarios where precise magnetic field sensing is required.

Key Features:

 Axes of Measurement: Measures magnetic field strength along three perpendicular axes: X, Y, and Z.

 Communication Interface: Typically communicates with external devices, such as microcontrollers, using the I2C (Inter-Integrated Circuit) communication protocol.

 Measurement Range: The BMM150 offers a configurable measurement range, often selectable between ±1300 µT (microteslas) or ±2000 µT.

 Resolution: The resolution of the BMM150 is 14 bits, providing high precision in magnetic field measurements.

 Power Consumption: The BMM150 is designed for low power consumption, making it suitable for battery-operated devices.

 Data Output: Outputs magnetic field strength values in digital form, which can be read and processed by a connected microcontroller.

 Calibration: The sensor may require calibration for accurate measurements, particularly to compensate for local magnetic disturbances.

 Interrupt Functionality: The BMM150 includes interrupt functionality, allowing the microcontroller to be notified when certain magnetic field conditions are met.

Pin Configuration (example):

• VDD: Power supply voltage (typical range is 1.65V to 3.6V).
• GND: Ground.
• SDI/SDO: I2C serial data input or serial data output.
• SCK: I2C serial clock input.
• DRDY/INT: Data ready or interrupt output.
