What's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself. Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!Note: It's a omnipolar magnet detector so that it can not tell two polarities apart.Specifications * Supply Voltage: 3.3V to 5V * Indicator LED on board * Interface: Digital * Size:22x30mm (0.87x1.18") Documents * Wiki Doc * DataSheet * Schematics Shipping List * Hall Sensor X1 * cable X1 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2025-01-23 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2025-09-28 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2025-11-01 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2025-12-02 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2025-12-21 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-01-22 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-01-30 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-02-21 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-02-23 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-02-26 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-02-28 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-03-02 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-04-12 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-04-16 https://elecena.pl/product/27743737/dfrobot-gravity-digital-hall-sensor 2026-04-19
