Elizabeth ★★★★★ Oct 20, 2026

The digital output makes interfacing with my microcontroller project dead simple, and the onboard LED is a nice visual confirmation. Exactly what I needed for a reliable magnetic trigger.

Robert U. ★★★★★ Oct 18, 2026

Swapped this into a simple magnetic switch for a cabinet door and the digital output triggers perfectly every time. The onboard LED is a nice touch for confirming detection during setup.

Aurora E. ★★★★★ Oct 17, 2026

I’ve been testing this on a low power 5V supply and the digital output switches cleanly when a magnet passes by. The onboard LED makes it easy to confirm the field detection without a multoscope.
