[0002] A Hall angle sensor is a magnetic sensor using the Hall effect principle. With them, the magnetic field and its changes can be detected and used in various magnetic-related occasions. The working principle of the Hall angle sensor is to utilize the Hall effect to convert non-electric and non-magnetic physical quantities such as the rotation angle into electric quantities for detection and control, with advantages such as vibration resistance, anti-interference, and high precision. When the rotating shaft on the Hall angle sensor rotates, it drives the magnetic steel on the rotating shaft to rotate together. Within a certain angle range, the magnetic field intensity of the magnetic steel changes linearly.
