Reed Relay Module (Reed Switch)

The reed relay module operates by bringing a magnet close to the module, which switches the contacts between its two terminals. This makes it ideal for encoder systems, magnetic detection systems, and similar applications.

For easy use, the module features VCC, GND, and digital output pins, allowing it to be used with many microcontroller platforms, especially Arduino. The module is normally open and closes the circuit when a magnet is nearby. It can be integrated into magnetic switches, door alarm systems, and many other systems.

The reed relay on the module can be mounted vertically or horizontally, depending on the application. It provides a digital output: when a magnet is near, the data pin outputs 5V, and the onboard LED lights up.

The product comes with three jumper wires, making it easy to connect to various systems.
