Description Unit Hall is a Hall sensor. It integrates three A3144E Hall effect switches, with logic processing performed by a 74 series gate integrated circuit. When an S magnetic pole object approaches the front of the hall or an N magnetic pole approaches the back of the hall, it can generate a low-level signal, and the internal LED indicator will light up. Hall sensors are utilized in door magnetic alarms, proximity sensing, speed measurement, and other scenarios. Features Unipolar Hall switch sensing Fast response speed, high sensitivity With status indicator light Low-level output Can be used with building blocks Includes 1 x Unit Hall 1 x HY2.0-4P Grove connection cable (20cm) 1 x Magnet Applications Door magnetic alarm Magnetic field proximity sensing Speed measurement Specifications Specification Parameter Hall Sensor A3144E * 3 Logic IC 74HC08D Status Indicator Red LED Output Level Low-level active Product Size 32.0 x 24.0 x 8.0mm Product Weight 4.2g Package Size 138.0 x 93.0 x 9.0mm Gross Weight 10.0g Learn and Documents → DOCUMENTS
