The magnetic sensor based on the Hall induction principle can be used to detect magnetic materials (magnets), regardless of polarity, and the range can reach about 3cm (the detection range is related to the strength of magnetism). It has the advantages of being sensitive to magnetic field, simple structure, small size, wide frequency response, large output voltage change and long service life.
