Hall sensor | Unit Hall Effect

The Hall effect Unit is a Hall sensor. Three A3144E hall induction switches are integrated in the interior, and logic processing is carried out through the 74 series gate integrated circuit. When an S magnetic pole object is near the front of the hall or the N magnetic pole is near the back of the hall, a low level signal can be generated, and the internal LED indicator light will be lit. Hall sensors are widely used in door status sensor alarm, proximity sensor, speed measurement and other scenarios.
