Mellow 3D Printer Parts Material detection module for 1.75mm/3.00mm filament detecting module monitor sensor Mechanical Endstop

Used with Lerdge board:

When there is material in, the green light in the module keeps lighting. And when the material is exhausted, the green light goes off, then the motherboard executes the pause command operation, after the replacement of the material, can continue to print.

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 a determined transition from high to low level, it will regard it as the material exhausted, then the board executes the pause command operation, and after the replacement of the material, it will continue to print.
