Magnetic Detection Reed Switch Sensor.

The Magnetic Detection Reed Switch is a compact and efficient magnetic sensing device used to detect the presence or movement of magnets. It contains a sensitive reed contact mechanism that activates when exposed to a nearby magnetic field, enabling accurate and contactless switching operations. This sensor is commonly used in security alarm systems, smart doors, window monitoring, robotics, industrial automation, and IoT projects. It can easily interface with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms for real-time magnetic detection and automation control.
