Using the Hall effect switch principle, the module senses magnetic field changes and converts magnetic induction into a digital voltage signal that can be read by common MCU input pins. The DC 3.3V-5V operating range makes it easy to test on breadboards or integrate into low-voltage control circuits. Use it for non-contact trigger switches, smart car prototypes, motor speed feedback, magnet counters, and door or cover position detection. The circuit description includes a Hall voltage generator, signal conditioning, Schmitt trigger, temperature compensation, and open-collector output stage, giving makers a straightforward magnetic sensing module for learning, prototyping, and electronics experiments. Always confirm wiring, polarity, and pull-up requirements based on your control board and project circuit.\u003c\/p\u003e\u003cp\u003eFree shipping on orders $50+. 30-day hassle-free returns.\u003c\/p\u003e","brand":"Belmont Warehouse","offers":[{"title":"Default Title","offer_id":43359101288657,"sku":"BW-B0HB5Z7NWV","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/3123\/5793\/files\/617MVwl8KML._SL1024.jpg?v=1790997680","url":"https:\/\/belmontwarehouse.com\/products\/10pcs-hall-effect-sensors-a3144-3144e-ky-003-magnetic-sensor-modules","provider":"Belmont Warehouse","version":"1.0","type":"link"}
