Hall Effect Sensor Module is used to Detect the proximity of a magnetic field if it present or absent nearby. The A3144 hall sensor module is a small size module. When the magnetic field rises above a threshold level, the open-collector output transistor switches on, which pulls the logic-compatible output low and illuminates the on board LED indicator.
