KY-021 - Reed Switch Shield
The KY-021 Reed Switch Shield is a sensor module that uses a reed switch to detect magnetic fields. The switch consists of two small ferromagnetic blades enclosed in a glass tube that come into contact when exposed to a magnetic field, completing an electrical circuit. This module is commonly used in proximity detection, door/window sensors, and other security or automation projects that involve detecting the presence or absence of a magnetic field.
