KY-025 Large Magnetic Reed Switch Module
Overview:
The KY-025 Large Magnetic Reed Switch Module is a highly sensitive sensor that detects the presence of a magnetic field and provides both digital and analog output signals. This module contains a reed switch that closes when exposed to a magnetic field, allowing the detection of magnetic proximity. The module is widely used in security systems, door/window sensors, and other proximity detection applications. It is compatible with microcontroller platforms like Arduino, Raspberry Pi, and ESP32.
