The onboard LM393 comparator converts this analog response into a clean digital output - LOW when a magnet is detected and HIGH when it is absent. Simply connect VCC, GND, and the digital output pin to your microcontroller, and you can instantly read magnetic presence in your code. Attach a small magnet to a rotating shaft, a door, or a moving part, and the module becomes a versatile proximity, speed, or position sensor.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Choose This Hall Effect Sensor Module?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e100% Authentic:\u003c\/strong\u003e Sourced directly from trusted, authorized component suppliers - no clones or counterfeits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBeginner-Friendly:\u003c\/strong\u003e Simple 3-pin digital interface requires no external components; connect and start reading in minutes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliable \u0026amp; Durable:\u003c\/strong\u003e No mechanical contacts mean no wear, no bounce, and virtually unlimited switching cycles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVersatile Detection:\u003c\/strong\u003e Works with neodymium magnets, ferrite magnets, and even electromagnetic coils for diverse applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1-5 days shipping:\u003c\/strong\u003e Ships from our Bengaluru warehouse to most locations across India; same-day delivery available in Bengaluru.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExpert Technical Support:\u003c\/strong\u003e Our engineering team is available 24\/7 via email and WhatsApp to help with wiring, code, and integration.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eProject Ideas\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRPM \/ Speed Measurement:\u003c\/strong\u003e Mount a magnet on a motor shaft or wheel spoke and count pulses per revolution to calculate RPM - perfect for tachometers, fan speed monitors, and vehicle speedometers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor \/ Window Security Alarm:\u003c\/strong\u003e Attach a magnet to the door and the sensor to the frame; trigger an alert or buzzer whenever the door opens and the magnetic field disappears.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContactless Proximity Switch:\u003c\/strong\u003e Replace mechanical buttons with a magnet-activated switch for waterproof, dustproof, and tamper-resistant control panels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow Meter Pulse Counter:\u003c\/strong\u003e Pair with a water or gas flow sensor that uses a magnetic rotor to count flow pulses and\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen will I receive my order?\u003c\/summary\u003e\n\u003cp\u003eProducts ship within 1-5 days from our Bengaluru warehouse.
