Adafruit Wide-Range Triple-axis Magnetometer - MLX90393 - STEMMA QT

The MLX90393 Magnetometer is a powerful and compact sensor that allows you to measure magnetic fields in three dimensions. This wide-range magnetometer offers 16-bit resolution and can detect magnetic fields in ranges from ±5mT to ±50mT along all three axes (X, Y, and Z). This range makes it ideal for detecting strong magnetic fields, such as those produced by magnets, rather than just the Earth's magnetic field, which most magnetometers are designed to measure.

Key Features:

• Wide Range: Measures magnetic fields from ±5mT to ±50mT, a far broader range than typical magnetometers, making it great for detecting magnets and magnetic orientation.
• 16-Bit Resolution: Provides accurate readings with high precision.
• I2C Interface: Communicates via I2C, allowing easy integration with a variety of microcontrollers (3.3V or 5V). Multiple sensors can be connected on the same bus, with up to 4 sensors on a single I2C line thanks to the adjustable I2C address pins.
• High Sample Rate: Can sample at up to 500 Hz, offering fast response times for real-time applications.
• Compact Design: The sensor comes on a small breakout board with STEMMA QT connectors, making it easy to connect without soldering. You can quickly hook it up to your microcontroller using a STEMMA QT adapter cable (sold separately).
• Fully Assembled: The breakout board is fully assembled and tested, ready for use out of the box. It includes a small piece of header for breadboard use.

Applications:

This magnetometer is ideal for detecting strong magnetic fields, such as those produced by magnets or motors, making it a great choice for magnetic orientation, magnet detection, or even compass-like applications when used with Earth’s magnetic field.

Specifications:

• Resolution: 16-bit output for all three axes (XYZ).
• Range: Measures magnetic fields from ±5mT to ±50mT (1 mT = 10 Gauss).
• Sample Rate: Up to 500 Hz, based on specific settings.
• Adjustable I2C Address: Allows you to connect up to 4 sensors on a single I2C bus by adjusting the address pins.
• Power Supply: Supports 3.3V or 5V microcontrollers with built-in power regulation and level shifting.
• Shipping Update: Due to chip shortages, the default I2C address is now 0x18 (instead of 0x0C).

This magnetometer offers versatility and ease of use, providing precise magnetic field data with minimal setup. Perfect for hobbyists and professionals alike!
