A3144 Hall Effect Magnetic Field Sensor Arduino

Magnetic field sensor using the Hall effect.
It has an open collector output, the state of which changes after the disappearance of the magnetic field. The output can be loaded with current up to 25 mA for a long time. It is characterized by a wide range of operating temperatures and small dimensions. It has internal temperature compensation.
Unipolar sensors: switching on occurs when a magnetic field appears, switching off when the magnetic field disappears. Widely used in automation, automotive, etc.
