The 3D Hall 2 Click Board™ is a very accurate magnetic field sensing Click Board™, used to sense the magnetic field strength in three perpendicular axes. It relies on a TLV493D-A1B6, a low power 3D magnetic sensor from Infineon. This sensor has a separate Hall sensor for each axis, which allows a very reliable magnetic field sensing in 3D space, offering the basis for accurate angle calculations.
The TLV493D-A1B6 sensor uses an industry-standard I2C communication interface and requires a very low count of external components. The I2C interface is also used for the chip reset, so the sensor features a very low count of pins.
