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.
