arduino Magnetic Sensor Modules Tinkerkit Hall Sensor Module  (Multicolor)

Magnetic Sensor Modules TINKERKIT HALL SENSOR MODULE Can be configured to detect magnetic fields or nearby people | Two rare earth magnets are included | Requires Arduino TinkerKit Shield The TinkerKit Hall Sensor creates a voltage related to the magnetic field around the sensor. This can be used to detect distance from a nearby magnet, a magnetic field induced in a wire or coil, or even a living thing.
