Overview
Detect the presence of any magnet in nearby space using the 3D Hall Click Board™. This add-on board features the MLX90333 Triaxis Hall sensor, which acts as a contactless position sensor for any type of magnet. It senses the position of a nearby magnet by being sensitive to three components of flux density (BX, BY, BZ). 3D Hall Click Board™ measures the rotational, linear and 3D displacement with high precision. The contactless coupling ensures resistance against wear and tear and environmental contaminants like dust and dirt. The MLX90333 sensor on the 3D Hall Click Board™ includes the Integrated Magnetic concentrator (IMC), which makes it a better alternative to any other conventional Hall sensor. It can derive the signal for all three axes by arranging two pairs of Hall sensors in a cross shape. 3D Hall Click Board™ uses the MikroBUS SPI interface (CS, SCK, MISO, MOSI) for communication with the target board MCU. Each MLX90333 chip has a 40-bit ID number. This Click Board™ provides 16-bit resolution positional data. It uses a 5V power supply only.
With these features, 3D Hall Click Board™ is an ideal choice for designing a 3D position sensor, joystick, 4-way scroll key, joypad, man-machine interface device, linear position sensor, and many more.
IC/Module: MLX90333 Triaxis Hall Sensor
Based on Triaxis Hall technology, the MLX90333 is an absolute 3D position sensor with a simple and robust magnetic design. It is sensitive to the 3 components of the flux density applied to the IC (BX, BY and BZ), which ensures easy sensing of magnet moving in its surrounding.
Integrated Magneto-Concentrator (IMC)
What makes the MLX90333 sensor aboard 3D Hall Click Board™ a better choice over conventional Hall sensor is the inclusion of an Integrated Magneto-Concentrator (IMC) deposited on the CMOS die. While conventional Hall sensors is only sensitive to only to magnetic flux applied orthogonally to the IC surface, this Triaxis Hall sensor is also sensitive to the flux density applied parallel to the IC surface.
Note: Other Hall effect-based sensors available include: LIN HALL Click Board™ (linear Hall effect sensor), UNI HALL Click Board™ (unipolar), and BI-HALL Click Board™ (bipolar).
