This user page needs to be updated.

Please update this page to reflect recent updates or newly available information.
Reason: Block mechanics as of Java Edition 22w13a.

The sculk sensor is a sculk node that detects vibrations caused by actions and events, and emits a mesecon signal.

Obtaining[]

Chest loot[]

Item	Structure	Container	Quantity	Chance
Java Edition
Sculk Sensor	Ancient City	Chest	1–3	23.2%
Bedrock Edition
Sculk Sensor	Ancient City	Chest	1–3	23.2%

Natural generation[]

Sculk sensors generate within the deep dark biome and ancient cities.

Breaking[]

Sculk sensors can be mined with any tool, but hoes are the quickest. They are obtained by mining them with a hoe enchanted with Silk Touch, otherwise they only drop 5 experience.

Block	Sculk Sensor
Hardness	1.5
Tool
Breaking time^[A]
Default	2.25
Wooden	1.15
Stone	0.6
Iron	0.4
Diamond	0.3
Netherite	0.25
Golden	0.2

↑ Times are for unenchanted tools as wielded by players with no status effects, measured in seconds. For more information, see Breaking § Speed.

Post-generation[]

A sculk catalyst has a 9% chance of generating a sculk sensor on top of a sculk node.

Usage[]

Light[]

A sculk sensor has a light level of 1. However, when active, it changes to a lighter node state without a change to the light level.

Vibration detection[]

Vibration JE1 BE1 — The sculk sensor vibration particle.

Sculk sensors can detect vibrations in a 9 node radius around it. A vibration is caused by many noisy events, such as a player gliding with elytra, a piston extending or a wet wolf shaking itself off. While sneaking, a player is not detected when walking, falling, or shooting a projectile.

When a vibration is made within the range of a sculk sensor, a signal travels from the vibration source to the sensor at a speed of one node per game tick (20 nodes per second). When the signal arrives, the sensor is activated for 40 game ticks (2 seconds). The sensor cannot detect any other vibrations while activated or while a signal is traveling to it.

Sculk sensors have a cooldown period of 1 tick after being placed or after deactivating. During this short cooldown period, they cannot detect vibrations. This prevents them from activating when a contraption it is powering is being unpowered.

Sculk sensors don't detect vibrations from other sculk sources or the warden.

Wool has a special interaction with sculk sensors. If a wool node is between a sensor and a vibration source, then that sensor is not able to detect the vibration. Sculk sensors are not able to detect footsteps on wool nodes, nor can they detect when wool node items are dropped. No vibrations are produced when wool is placed, even if placed on top of the sculk sensor.

A sculk sensor activates when any item is dropped directly on top of it, including wool.

Vibrations made by players are passed on to nearby sculk shriekers. This can be blocked by wool placed in between the sensor and shrieker, similar to how wool can block vibrations from reaching the sensor itself.

Mesecon emission[]

Sculk sensors emit a mesecon signal when they are activated. The strength of the mesecon signal is inversely proportional to the distance the vibration signal traveled – the closer the vibration is to the sculk sensor, the stronger the mesecon signal is, so it reaches the maximum mesecon signal strength when the vibration is directly on top of the sensor.

Vibration amplitudes[]

This section needs expansion.

You can help by expanding it.
Instructions: Bedrock Edition values

Sculk sensors have a unique interaction with comparators. Each vibration in the game falls under a certain amplitude value. This value can be measured with a comparator as mesecon output. With the right contraption, the player could detect if a certain action has occurred or is occurring nearby.

Piston interactivity[]

Sculk sensors are immovable. Pistons cannot push them, and sticky pistons cannot push or pull them. Slime blocks and honey blocks do not stick to sculk sensors and have no effect whether the slime block or honey block is being pushed or pulled.

Sounds[]

A sculk sensor is silent if waterlogged. It can still detect vibration, but does not produce sounds itself. Java Edition:

Trivia[]

"Sculk" is derived from "skulk," meaning "keep out of sight, typically with a sinister or cowardly motive".^[7]
Boombomb footsteps do not trigger sculk sensors, unless they walk off a ledge, even if they don't take fall damage.
