Pzsmocn Hall Sensor Compatible with Arduino and Raspberry Pi. Detection Range About 3cm (Detection Range Related to Strength of Magnetism), for Non-contact Switch and Magnetic Related Project.

• A magnetic sensor based on the Hall induction principle can be used to detect magnetic materials. (Magnet)
• Regardless of polarity, the range can reach about 3cm, and 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.
• Suitable for making interactive works related to magnetic materials (Magnets).
• Note: It's a omnipolar magnet dectector so that it can not tell two polarities apart.
