The Magnetic Reed Switch Sensor Module is a compact and easy-to-use sensor designed to detect the presence or absence of a magnetic field. It uses a sensitive reed switch along with an adjustable control and LED indicators, making it suitable for a wide range of electronic and automation projects. Simply bring a magnet close to the sensor to trigger the reed switch and generate a digital output signal. The onboard LEDs provide a clear indication of the sensor and output status, while the adjustable potentiometer allows you to fine-tune the module according to your application.
