Building on the experiments with the AS5510, we explore the use of the AS5013 to perform 3-dimensional tracking of a magnet. This IC is nominally an 8-bit 2 axis magnetic encoder, though it contains 5 hall effect sensors, each with 12-bit resolution, adjustable gains, and I2C-accessible raw values. <ahref='as5013-test'>as5013-test/</a> contains pcb source files for a board to evaluate this measurement.
Building on the experiments with the AS5510, we explore the use of the AS5013 ($4.42 in Q100) to perform 3-dimensional tracking of a magnet.

To characterize the use of the AS5013 as a three-dimensional tracking device, we use a 5 axis stage (2 axes motorized, 3 manual) built around two Thorlabs PT1M micrometer stages. After setting a magnet height and orientation, we can sample the 5 hall elements over a two dimensional array of magnet displacements. Executing this for a handful of magnet heights should let us fit functions for X, Y, and Z in terms of the 5 hall readings.
