The 3D Hall 3 Click Board™ is a very accurate, magnetic field sensing Click Board™, used to measure the intensity of the magnetic field across three perpendicular axes. It is equipped with the LIS2MDL, a low power 3D magnetic sensor. This IC has a separate Hall sensing element on each axis, which allows a very accurate and reliable measurement of the magnetic field intensity in a 3D space, offering a basis for accurate positional calculations. Both I2C and SPI communication protocols are supported by the LIS2MDL. This sensor IC features a powerful programmable interrupt engine, allowing firmware optimization.
