Redstone Comparator is a redstone logic component that reads, compares, or subtracts signal strength, including the fill level of chests, cauldrons, and other container blocks. It instantly breaks when mined and always returns itself.

Uses

  • Crafting — Crafted from 3 Redstone Torches, 1 Nether Quartz, and 3 Stone arranged on a crafting table.
  • Comparison and subtraction mode — Right-clicking toggles between comparison mode (outputs the stronger of two side inputs) and subtraction mode (rear signal minus side signal), enabling complex redstone logic.
  • Container level detection — Placed facing a chest, barrel, or hopper, it outputs a signal proportional to how full the container is, powering item sorters and storage indicators.

Found In

  • Crafted only — Does not generate naturally; must be crafted using Redstone, Nether Quartz, and Stone.

Drops

FAQ

What tool do I need to mine a Comparator?

None. It instant-mines with any tool or bare hands and always drops itself.

What ingredients craft a Comparator?

Three Redstone Torches, one Nether Quartz, and three Stone blocks arranged in the standard comparator recipe.

What's the difference between comparison and subtraction mode?

Comparison mode outputs the larger of the rear or side signal; subtraction mode outputs the rear signal minus the strongest side signal.

Can a Comparator read container contents?

Yes. Facing a chest, barrel, hopper, or similar container, it outputs a signal strength proportional to how full that container is.
