It operates at 3.3V and 5V logic levels, making it compatible with most starter kits. Pair it with a WitBlox Bluetooth module for wireless alerts.\u003c\/p\u003e\u003ch2\u003eWiring Notes\u003c\/h2\u003e\u003cp\u003eConnect VCC to 5V (or 3.3V), GND to ground, and DO (digital output) to a digital input pin on your microcontroller. The output goes LOW when a magnetic field is detected. A 10K pull-up resistor is often included; if not, enable internal pull-up on the reading pin. Keep leads short to avoid false triggers.\u003c\/p\u003e\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino?\u003c\/summary\u003e\u003cp\u003eYes, the sensor operates at 5V and provides a digital output that can be read by any Arduino digital pin. Example code is included in the kit guide.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eWhat magnets are included?\u003c\/summary\u003e\u003cp\u003eThe kit includes 2 small neodymium disc magnets sufficient for all six projects. They provide a strong trigger for the Hall effect sensor at close range.\u003c\/p\u003e\u003c\/details\u003e\u003cdetails\u003e\u003csummary\u003eCan I use this to count rotations?\u003c\/summary\u003e\u003cp\u003eAbsolutely. Place a magnet on a wheel and position the sensor nearby; the digital output toggles with each pass, allowing your microcontroller to count pulses.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdiv class=\"compoden-handoff\" style=\"margin-top:24px;padding:16px;background:#f0f4ff;border-left:4px solid #2B4D8F;border-radius:4px;\"\u003e\n  \u003cp style=\"margin:0 0 6px 0;font-weight:600;color:#1A3560;\"\u003e📦 Free Setup Handoff Document Included\u003c\/p\u003e\n  \u003cp style=\"margin:0;font-size:0.95em;color:#333;\"\u003eEvery Compoden order includes a free setup handoff document — step-by-step instructions to get your component working within minutes.
