This module utilizes the A3144 Hall-effect sensor, a reliable component that changes its output state (switches from HIGH to LOW or vice versa, typically active-low) when a magnetic field is introduced. Unlike analog Hall sensors, the KY-003 provides a clear, binary digital output, making it exceptionally easy to integrate into microcontrollers like Arduino, ESP32, and Raspberry Pi without the need for analog-to-digital conversion.\u003c\/p\u003e\n\u003cp\u003eIts simple 3-pin interface (VCC, GND, Signal) and compact design make it a versatile choice for a wide array of applications, including non-contact switching, precise position detection, and speed measurement. Whether you're building a security alarm, a motor RPM counter, or a robotic system, the KY-003 offers reliable and fast response to magnetic stimuli, making it an essential tool for hobbyists and professionals alike.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\n\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cp\u003eModule Type: KY-003 Hall Magnetic Sensor Module\u003cbr\u003eOperating Voltage: 4.5V - 24V DC\u003cbr\u003eOutput Type: Digital (Active-low, typically: LOW when magnetic field is present, HIGH when absent, but check specific sensor datasheet for exact behavior).\u003cbr\u003ePins: 3 (VCC, GND, Signal)\u003cbr\u003eProduct Dimensions: 25x15mm\u003cbr\u003ePackaging Dimensions: 8x6x1cm\u003c\/p\u003e","brand":"Makerlab Electronics","offers":[{"title":"Default Title","offer_id":44223429116095,"sku":"MLE06998","price":19.0,"currency_code":"PHP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/MLE06998_1.jpg?v=1748245651","url":"https:\/\/makerlab.ph\/products\/ky-003-hall-magnetic-sensor-module","provider":"Makerlab PH","version":"1.0","type":"link"}
