Types of Containers
- Brewing Stands
- Ender Chests
- Shulker Boxes
When a Container is connected to a Redstone Comparator it generates a Redstone signal. The strength of the Redstone signal depends on how full the container is, and how many items it contains. For example, a Chest with 10 items will send a greater signal than a Chest with 5 items.
Note that Items that can not be stacked give a stronger signal than Items that can be stacked. An Item that can be stacked up to 16 Items, gives a stronger signal than those stackable up to 64 Items. A full Chest will generate a full strength signal reaching 15 Blocks.
