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.\u003c\/span\u003e\u003c\/p\u003e","brand":"M5 Stack","offers":[{"title":"Default Title","offer_id":53917053747540,"sku":"BP-M5-U084","price":7.45,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/3036\/5524\/files\/hall_effect.webp?v=1773225404","url":"https:\/\/shop.sensa.systems\/products\/hall-effect-unit","provider":"Sensa Systems","version":"1.0","type":"link"}
