3D Printer Filament Detection Sensor Module - Auto Pause & Resume for Smooth Printing | Perfect for Ender 3, CR-10, DIY 3D Printing Projects

The material detection module uses the level transition detection method. When with material in, the detection level signal should be high, and when no material, the material port level signal goes low. When the system detects the filaments transition from high to low level, it will regard it as out of filaments state, then the board executes the pause command operation, and after the replacement of the material, it will continue to print?
