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 magnetic 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!Features * Wide voltage range from 3.3V to 5V * Standard assembling structure (Times-of-5mm Center distance between two 3mm mounting holes) * Easily re cognitive interfaces of sensors ("A" for analog and "D" for digital) * Icons to simply illustrate sensor function * High quality connector * Immersion gold surface Specification * Supply Voltage: 3.3V to 5V * Indicator LED on board * Interface: Digital * Size:22x30mm (0.9x1.2in) Documents * Wiki Doc * Schematic Shipping List * Digital magnetic sensor x1 * Digital cable x1 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-01-23 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-09-28 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-11-04 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-11-14 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-11-21 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-11-29 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-12-02 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2025-12-21 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2026-01-22 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2026-01-30 https://elecena.pl/product/27743735/dfrobot-gravity-digital-magnetic-sensor 2026-03-21
