The Magnetic Hall Effect Sensor Module is designed to detect magnetic fields and convert them into digital output signals for microcontroller systems. It uses a linear Hall sensor with an onboard comparator circuit that provides a clear low-level signal when a magnetic field is detected. The module operates at 5V DC and includes an adjustable potentiometer to control sensitivity and detection threshold. An onboard LED indicates signal output status for easy debugging. It is suitable for Arduino projects, magnetic detection systems, speed sensing, and automation applications.
