The Magnetic Reed Switch Module is a simple and reliable sensor used to detect the presence of a magnetic field. It consists of a reed switch that closes or opens when exposed to a nearby magnet, enabling easy detection of position or movement.

This module is widely used in Arduino, AVR, PIC, and embedded systems for applications such as door/window security systems, position sensing, speed detection, and automation systems.

It provides both digital and analog outputs (depending on module variant) and includes an onboard indicator LED for status monitoring. The module is easy to interface and requires minimal setup, making it suitable for beginners and professionals alike.

With its compact design and low power consumption, the reed switch module is ideal for real-time sensing and automation projects.
