Magnetic Reed Sensor

The Magnetic Reed Sensor Module is a compact, highly reliable magnetic switch designed to detect the presence or absence of a magnetic field. It operates by opening or closing its internal contacts when influenced by a magnetic field, making it ideal for door/window sensors, security systems, home automation, robotics, and position detection applications. The reed switch is enclosed in a protective casing and reacts when a magnet is brought near it, triggering a change in output. It offers digital output, is easy to interface with microcontrollers like Arduino, Raspberry Pi, and ESP32, and is widely used in DIY electronics, smart homes, and automation systems.
