Unlike raw glass reed switches that are fragile and hard to solder, this module comes pre-mounted on a durable PCB with all necessary circuitry included.\u003c\/p\u003e\n\u003cp data-path-to-node=\"10\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"11\"\u003eHow It Works\u003c\/h3\u003e\n\u003cp data-path-to-node=\"12\"\u003eAt the heart of this module is the \u003cb data-path-to-node=\"12\" data-index-in-node=\"35\"\u003eMKA10110 Green Reed Switch\u003c\/b\u003e. Inside the sealed glass tube are two ferrous elastic reeds separated by a small gap. When a magnet approaches, the magnetic field lines magnetize the reeds, causing them to attract and touch. This closes the circuit (Signal goes High\/Low depending on logic), lighting up the on-board LED and sending a digital signal to your microcontroller. When the magnet moves away, the reeds spring apart, breaking the circuit.\u003c\/p\u003e\n\u003cp data-path-to-node=\"12\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"13\"\u003eBuilt for Makers and Educators\u003c\/h3\u003e\n\u003cp data-path-to-node=\"14\"\u003eWe understand the frustration of confusing wiring. That’s why this module features a \u003cb data-path-to-node=\"14\" data-index-in-node=\"85\"\u003e3-pin anti-reverse interface\u003c\/b\u003e. The included custom wire ensures you never plug it in backwards, protecting your sensor and your mainboard. It operates seamlessly between \u003cb data-path-to-node=\"14\" data-index-in-node=\"254\"\u003e3.3V and 5V\u003c\/b\u003e, making it universally compatible with most modern development boards.\u003c\/p\u003e\n\u003cp data-path-to-node=\"14\"\u003e \u003c\/p\u003e\n\u003ch3 data-path-to-node=\"15\"\u003eCommon Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"16,0,0\"\u003e\n\u003cb data-path-to-node=\"16,0,0\" data-index-in-node=\"0\"\u003eSmart Home Security:\u003c\/b\u003e Detect if windows or doors are opened.\u003c\/li\u003e\n\u003cli data-path-to-node=\"16,1,0\"\u003e\n\u003cb data-path-to-node=\"16,1,0\" data-index-in-node=\"0\"\u003ePosition Sensing:\u003c\/b\u003e Use as a limit switch for CNC machines or 3D printers.\u003c\/li\u003e\n\u003cli data-path-to-node=\"16,2,0\"\u003e\n\u003cb data-path-to-node=\"16,2,0\" data-index-in-node=\"0\"\u003eSpeed Detection:\u003c\/b\u003e Calculate RPM by attaching a magnet to a rotating wheel.\u003c\/li\u003e\n\u003cli data-path-to-node=\"16,3,0\"\u003e\n\u003cb data-path-to-node=\"16,3,0\" data-index-in-node=\"0\"\u003eInteractive Art:\u003c\/b\u003e Trigger lights or sounds when an object is placed correctly.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Keyes","offers":[{"title":"Default Title","offer_id":46812878241943,"sku":"21PS002182","price":78.0,"currency_code":"TWD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0440\/4022\/4919\/files\/keyes-digital-reed-switch-module-arduino.jpg?v=1768385639","url":"https:\/\/scccltd.com\/en-tw\/products\/digital-magnetic-reed-switch-sensor-module","provider":"Sun Cheong Computer Company Limited","version":"1.0","type":"link"}
