More Information
Summary:An intelligent device having detachable bodies, where a Hall effect sensor and a magnet are respectively disposed on two detachable bodies, and the Hall effect sensor detects a magnetic field of the magnet to determine whether the two bodies are in an attracted state. In addition, an attraction magnet pair is disposed on each of the two bodies to implement attraction of the two bodies. Each attraction magnet pair includes two magnets having opposite polarities and disposed side by side. Such an attraction magnet combination reduces strength of a magnetic field in a direction of a non-magnetic pole, thereby reducing impact on detection on the magnetic field by the Hall effect sensor.
