About this product
KY-025 is a reed switch module that gives a digital output when a magnet comes close to its reed sensor. It works from 3.3 V to 5 V and provides a clean 0/1 signal that can be read directly by the digital pins of Arduino, ESP32 and similar boards. It has fixed mounting holes for simple installation and is commonly used for magnet-triggered detection projects.
