★Main Function:Used to detect if the filament is running out, and automatically stop the 3D printer when the filament runs out
★Filament detection module: the new design of the intelligent module, when the filament is used up, the main board to implement the pause command operation
★3D Printer Accessories:Very useful filament detection sensor module, ideal accessory for 3D printers to make your printing work smooth and assured
★Suitable for use with other boards: The material detection module uses level-hopping detection. When there is a material, the level signal of the detection port should be high. When there is no material, the level signal of the material port is low and the system detects a material. If the transition from high to low is determined, the material is considered to be used up and the pause command is executed. After the person replaces the material, the printer continues to print
