Reed Switch Module
The Reed Switch Module is a magnetic sensing module designed to detect the presence or absence of a magnetic field. It uses a reed switch enclosed inside a glass tube that changes its switching state when exposed to a magnet, making it suitable for contactless detection applications. With a simple digital output interface, this module can be easily connected with Arduino, ESP32, STM32, and other microcontroller platforms for security systems, automation, robotics, and sensor-based projects. Available at Directronics, the Reed Switch Module is ideal for students, hobbyists, makers, educators, and professional engineers.
