Hall sensors, as one of the indispensable components in modern electronic technology, play an important role in the fields of position detection, speed measurement, and current sensing by virtue of their non-contact magnetic field detection capability. Its working principle is based on the Hall effect, that is, when there is a current through the semiconductor material placed in the magnetic field, it will produce a voltage difference in the direction perpendicular to the current and the magnetic field. In practical applications, Hall sensors are usually used in conjunction with magnets to achieve precise positioning of magnetic objects or monitoring of the state of motion, this article is about the Hall sensor and the distance between the magnet some introduction, I hope it will help you.
Ideally, the optimum distance between the Hall sensor and the magnet is usually between 1 and 5 millimeters. This range ensures that the sensor can accurately detect changes in the magnetic field without saturating the signal by being too close.

However, the specific optimum distance needs to be considered in addition to the following factors.
1. Magnet strength: Stronger magnets allow for slightly greater distances.
2. Sensor sensitivity: Higher sensitivity sensors can operate at greater distances.
3. Application environment: Consider the effects of external factors such as temperature, vibration, etc.
4. Accuracy requirements: Higher accuracy may require closer distances.
In practice, it is recommended to experiment to determine the optimum distance for a particular setup, and some Hall sensors usually provide recommended distance ranges inside their product manuals.
