Hall Effect Magnetic Field Sensor Module KY-003
Hall Effect Magnetic Field Sensor Module is a Hall Effect sensor module with 3144 magnetic sensors, which normally outputs 0 from the digital output pin and 1 from its digital output when it is close to an object that creates a magnetic field, such as a magnet. It can be easily used with many microcontrollers such as Arduino.
The Hall effect creates a voltage difference that can be measured perpendicular to the magnetic field when a conductor, through which an electric current is flowing, is placed in a magnetic field. With this logic, detection is provided. Hall effect sensors are solid-state magnetic electronic components that can switch magnetically or measure magnetic fields.
