What is a 3D Hall effect sensor and why are there not many manufacturers launching 3D Hall effect sensors? 1

A 3D Hall effect sensor is a high-precision sensor that utilizes the Hall effect to measure the distribution of magnetic fields in three spatial dimensions. The Hall effect refers to the voltage difference generated on the side of a conductor placed in a magnetic field when current passes through it, .diode  which is proportional to the strength of the magnetic field. The traditional AD7865ASZ-1 Hall effect sensor can usually only measure the distribution of magnetic field in one direction, while the 3D Hall effect sensor can simultaneously measure the distribution of magnetic field in three vertical directions, providing more comprehensive magnetic field information.diode

Working principle of 3D Hall effect sensor

The core of a 3D Hall effect sensor is a specially designed semiconductor material that can generate voltage differences in its three orthogonal directions under the action of a magnetic field. These three voltage differences correspond to the strength of the magnetic field in these three directions. By measuring these voltage differences, the three-dimensional distribution of the magnetic field can be directly obtained. This type of sensor typically requires complex signal processing circuits and algorithms to analyze magnetic field data in order to provide high-precision measurement results..diode
