When a magnet (specifically the correct pole) is brought near the sensor, the magnetic field generates a small voltage within the A3144. The LM393 chip then compares this voltage to a preset threshold to determine whether to trigger a signal.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eWhy it’s a Motion \u0026amp; Security Essential:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Non-Contact Sensing: Because it relies on magnetism, it can detect movement through plastic, wood, or glass. This allows you to hide the sensor inside a waterproof enclosure or behind a door frame.\u003cbr\u003e• Dual Output Utility:\u003cbr\u003eo Digital (DOUT): Perfect for \"switched\" events, like a door being opened or a wheel completing a full rotation. The onboard potentiometer lets you set exactly how close the magnet needs to be to trigger this pin.\u003cbr\u003eo Analog (AOUT): Provides a continuous voltage that changes as the magnet gets closer. This is ideal for measuring the \"strength\" of a magnet or very fine-tuned positioning.\u003cbr\u003e• High-Speed Counting: Unlike a reed switch (which has moving metal parts that can bounce), this is a solid-state sensor. It can trigger thousands of times per second, making it the primary choice for measuring motor RPM.\u003cbr\u003e• Visual Debugging: The onboard signal LED lights up the moment a magnet is detected, allowing you to calibrate your project without needing a computer.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cstrong\u003eTechnical Capabilities:\u003c\/strong\u003e\u003cspan\u003e\u003cbr\u003e• Operating Voltage: Wide range from 2.3V to 5.3V (Native support for Arduino, ESP32, and Raspberry Pi).\u003cbr\u003e• Magnetic Sensitivity: Triggers between 35 and 450 Gauss, which is the strength of a typical small neodymium magnet.\u003cbr\u003e• Built-in Hysteresis: Includes a safety margin of 20 Gauss to prevent the sensor from \"flickering\" when a magnet is right on the edge of the detection range.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan data-sheets-root=\"1\"\u003e\u003cspan\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003e\u003cstrong\u003eBest For:\u003c\/strong\u003e\u003cbr\u003e\u003c\/span\u003e\u003cspan\u003eThe LM393 Hall Effect module is the primary choice for tachometers (RPM counters), magnetic door\/window alarms, limit switches for 3D printers, and liquid level sensing (using a floating magnet).\u003cbr\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"TinkEdge","offers":[{"title":"Default Title","offer_id":46404676780231,"sku":"TE-IRSE-091","price":57.78,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0774\/6620\/6407\/files\/LinearHallEffectSensorModule_1.png?v=1776770040","url":"https:\/\/shop.tinkedge.tech\/products\/linear-hall-effect-sensor-module","provider":"TinkEdge","version":"1.0","type":"link"}
