Redstone Comparators are a special redstone block that are similar to redstone repeaters. Redstone comparators have a third torch on them, allowing for complex redstone features. Redstone comparators have three ports, with two being for input, the third for output. Redstone comparators also measure how many things an entity holds or weighs, allowing for some very interesting adventure maps or mechanisms. They can also detect how many items are stored in a container block (such as a chest, hopper, dropper or dispenser). It can be utilized in a Redstone Circuit. It makes the same sound as wood when broken.

A tutorial on YouTube is available that shows how to build with redstone comparators.
