Minecraft: How To Use Sculk Sensors To Make Wireless Redstone

thegamer.com:

The Wild Update brought the Deep Dark to Minecraft — a spooky biome lurking deep underground containing the remnants of cities from past civilisations, guarded by a terrifying monster. Lining almost every surface in this unsettling environment is a mysterious substance known as sculk, which interacts with sound in curious ways.

There are numerous blocks and materials within the sculk family — sculk catalysts turn nearby blocks into sculk when mobs are killed in the vicinity, and that sculk contains the XP the dead mobs would have dropped. Sculk shriekers emit a scream when triggered that can summon the Warden, but perhaps the most interesting of all are sculk sensors, which enable redstone to work wirelessly.

Sculk sensors are special sculk blocks that specialise in detecting and passing on vibrations. The ideas of sound and vibrations are sort of motifs in the Deep Dark, as shriekers are activated by receiving vibrations and sound is the Warden's main way of detecting its prey. What's special about sculk sensors, though, is that not only can they detect nearby vibrations for their activation, but when they do activate, they can interact with redstone.

Sculk sensors generate naturally anywhere in the Deep Dark, both within and outside of Ancient Cities. Any patch of sculk you can see has the chance to generate with sculk sensors on it. Furthermore, if a mob dies in the vicinity of a sculk catalyst, and there are no other sculk sensors nearby, the catalyst has a nine percent chance of producing a sensor as part of the sculk it generates — provided it has enough XP. This works both with catalysts in the Deep Dark, and ones that have been brought elsewhere.
