The mini reed relay module operates by bringing a magnet close to the module, which switches the contacts between its two terminals. This makes it suitable for encoder systems, magnetic detection systems, and similar applications.
For easy integration, the module includes VCC, GND, and digital output pins, allowing it to work with many microcontroller platforms, especially Arduino.
The module is normally open and switches to a closed circuit when a magnet is nearby. It can be integrated into magnetic switches, door alarm systems, and other similar systems.
The reed relay on the module can be mounted vertically or horizontally, depending on your needs. It provides a digital output, and when a magnet is near, the data pin outputs 5V.
It is compatible with a wide range of microcontroller platforms, especially Arduino.
