The Item Detector detects items passing through it, and must be placed between two or more pieces of Pneumatic Tube.
It will not remove the color tags of the items passing through it.
Item Detector Modes:
- Item Mode: Will emit a Redstone pulse for every item, e.g. 64 pulses for a stack of dirt.
- Stack Mode: Will emit a single pulse for every stack of an item passing through it, e.g. a single pulse for a stack of cobblestone.
- Stuffed Mode: Will emit a constant redstone signal whenever there is an item stuffed back into it, which happens if there are no available destinations left for the item.
