How to Use Sculk Sensors to Make Wireless Redstone in Minecraft

The Savage Update brought the Deep Darkness to Minecraft — an eerie biome lurking deep underground containing the remains of cities from past civilizations, guarded by a terrifying monster. Coating nearly every surface in this haunting environment is a mysterious substance known as sculk.that interacts with sound in curious ways.

There are numerous blocks and materials within the sculk family: sculk catalysts turn nearby blocks into sculk when nearby mobs die, and that sculk contains the XP that dead mobs would have dropped. Sculk Shriekers emit a scream when activated that can summon the Guardian, but Perhaps the most interesting of all are the sculk sensors, which allow redstone to work wirelessly.

THE GAMER VIDEO OF THE DAY

What are Sculk sensors and where can I find them?

Sculk Sensors are special Sculk blocks that specialize in sensing and transmitting vibrations. The ideas of sound and vibrations are sort of motifs in Deep Dark, as screams are triggered by receiving vibrations and sound is the main way Warden detects prey from him. However, the special thing about sculk sensors is that not only can they detect nearby vibrations for activation, but when activated, they can interact with redstone.

Sculk Sensors spawn naturally anywhere in the Deep Dark, both inside and outside of the Ancient Cities. Any patch of sculk you can see has a chance to spawn with sculk sensors. Also, if a mob dies near 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 spawns, as long as you have enough XP. This works both with catalysts in the Deep Dark and those that have been brought elsewhere.

How to Get Sculk Sensors

If you want to pick up a sculk sensor you’ve found so you can use it for your redstone, you will need to extract it with a tool enchanted with Silk Touch — hoes are the fastest for all sculk based blocks. However, finding sensors on the ground in Deep Dark and having catalysts spawn them aren’t the only ways to get them.

All chests inside Old Cities, except ice chests, have a 23.2% chance to spawn with between one and three sculk catalysts inside.. This allows you to get your hands on some without the need for Silk Touch.

How to Transmit a Redstone Signal Using Sculk Sensors

Sculk sensors will detect any vibration within a nine-block radius around you, and when they do, they will emit a redstone signal. The distance that sculk sensors can send a signal depends on how close the vibration is to the sensor. A vibration directly above the sensor will produce a signal with a strength of 15, while one nine blocks away will produce a signal with a strength of one.


Vibrations are more or less anything that makes noise: walking, jumping, eating, placing blocks, etc.. Doing any of these activities near a sculk sensor will activate it and cause it to emit a redstone signal. This makes them great for detecting players or mobs – vibrations travel through walls, so hiding a sculk sensor to detect nearby players and activate a defense mechanism would make an excellent trap. You can even flood it to prevent it from making noise and alert intruders.

How to use wool with Sculk sensors

However, maybe you don’t always want your sculk sensor to direct vibrations, or maybe you just want to detect vibrations from a specific direction. This is where wool occlusion comes into play. This fancy term just means using wool to dampen vibrations and prevent them from being picked up by a sensor, like wool is the only block that vibrations cannot pass through.

Vibrations will always travel to the sensor in a straight line, so any vibration that would have to pass through the wool simply won’t reach the sensor. Similarly, walking on a rug does not produce vibrations, nor does laying or destroying wool.

This is useful in many scenarios. For the aforementioned trap, you can occlude all directions besides the one you expect intruders to come from, to avoid triggering your own trap while moving around your base. Also very useful for larger redstone contraptions with lots of moving parts. you can make the sensor only activate when you want it to, instead of being activated by random pistons and dispensers.

Lana occlusion is part of what gives Sculk sensors such excellent potential. Because they emit redstone signals when activated, you can make a sensor trigger something that makes noise when shot, like a hatch, but occlude the sensor so that the hatch does not reactivate it. Instead, the hatch activates another sensor nine blocks away, and this can be repeated infinitely. Wireless red stone!


How to use comparators with Sculk sensors

As if redstone going wireless after over a decade in the game wasn’t enough, sculk’s sensors can do even more. Like many blocks, they can be connected to a comparatorwhich produces outputs of various signal strengths depending on what the block in question is doing.

With sculk sensors, the comparator can detect what vibration the sculk sensor is picking up. Each type of vibration corresponds to a different output force, which opens up nearly limitless possibilities for how sculk sensors can be used as detectors. Here is a complete list of the types of vibrations and the signal strengths they correspond to:

Vibration signal strength
Walk (players or mobs) 1
Flapping (for example, bat wings) two
Swimming 3
elytra slipping 4
  • Take fall damage (players or mobs)
  • Teleportation (eg Endermen)
5
  • Block state change (things an observer would detect, e.g. putting a disk in a jukebox)
  • Minecart moving, splashing (entering the water, boats in columns of bubbles)
  • Wolves shaking off water
  • playing note blocks
6
  • drinking
  • Fuses (TNT lit, Creepers preparing to explode)
  • projectiles are fired
7
  • feeding mobs
  • projectile landing
  • Eating
  • Take damage (players and mobs)
8
  • Equip armor or place it on an armor stand
  • using scissors
  • roaring ravager
9
  • Closing of gates, hatches and fence gates
  • Deactivation of buttons, levers, pressure plates or tripwire hooks
  • Detach the tripwire from a hook
  • Failed dispenser
10
  • Opening doors, hatches and fence gates
  • Activation of buttons, levers, pressure plates or tripwire hooks
  • Attaching a tripwire to a hook
eleven
  • placing blocks
  • Entity placement (from spawn eggs, as well as “blocks” that the game considers entities like paintings)
  • Liquid is placed, from a bucket on the ground, or in a cauldron with a bucket or stalactites
12
  • destroying blocks
  • Destroy entities (don’t kill mobs, just destroy things like armor stands)
  • Collect liquids: get honey from hives, fill a bucket, use glass bottles in cauldrons or dragon’s breath
13
  • Reeling on a fishing rod
  • Close a container (for example, Shulker chests or boxes)
  • Piston Hiring
14
  • opening a container
  • piston extension
  • Using a goat horn
  • Explosions – TNT, Creepers and Fireworks
  • lightning strikes
fifteen

With this, along with some clever comparator circuitry, you can pretty much detect anything you want. If you need to spot someone swimming specifically at your base, you can. If the space for the redstone behind the wall you want to place a button on is tight, you can have a button that isn’t actually connected to anything, but still activates a circuit with the sound of it being pressed. How about a circuit that detects when the rain has stopped, using a dog shaking itself to dry off?

Sculk sensors are a fantastic addition to the redstone component pool, and their interactions with redstone, lana, and comparators enable not only wireless redstone, but a level of detection never seen before. They may seem a bit complex at first, but jump in and experiment, and you’ll be making all sorts of exciting sculk contraptions in no time!
