The sculk sensor is a block that can detect vibrations and emit a redstone signal.
Obtaining
Sculk sensors can currently be obtained only from the creative inventory or commands.
Breaking
Sculk sensors can be mined with any tool, but hoes are the quickest.
| 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.
Usage
Light
An inactive sculk sensor has an inconspicuous light level of 1. However, when active it emits a brighter yellowish light that illuminates its surroundings.
Vibration detection
The sculk sensor vibration particle.
Sculk sensors can detect vibrations in an 8 block radius around it. A vibration is anything that causes physical motion, although there are some motions that are undetectable to sensors by sneaking; these sneak-friendly vibrations include walking, falling to the ground or throwing/shooting projectiles.
Wool has a special interaction with sculk sensors. If a wool block is between a sensor and a vibration source, then that sensor is not able to detect the vibration. In addition, sensors are not able to detect walking on wool or throwing wool on the ground. [Java Edition only]
When a vibration is detected, a signal is sent from the source location to the sensor at a speed of one block per game tick (20 blocks per second). Other vibrations cannot be detected by a sensor when a signal is already travelling to it. When the signal has arrived, the sensor is activated for 40 game ticks (2 seconds). While activated, the sensor cannot detect other vibrations.
Sculk sensors have a cooldown period of 1 tick after being placed or after deactivating. During this short cooldown period, it cannot detect vibrations. This is to prevent it from activating itself when a contraption it is powering is being unpowered.
Sculk sensors don't listen to vibrations that are directly created by other sculk sources.
A sculk sensor is silent if waterlogged, meaning that it can still detect vibration but does not make sounds while doing so.
Redstone emission
Sculk sensors emit a redstone signal when they are activated. The strength of the redstone signal is inversely proportional to the distance the vibration signal traveled – the closer the vibration is to the sculk sensor, the stronger the redstone signal is, so it reaches the maximum redstone signal strength when the vibration is directly on top of the sensor.
Vibration frequencies
Sculk sensors have a unique interaction with comparators. Each vibration in the game falls under a certain frequency value, and this value can be measured with a comparator as redstone output. With the right contraption, this allows the player to detect when a certain action has occurred nearby.

- ↑ a b c d Is ignored when crouching.
- ↑ a b c d e f g h i j k l m Also works with dispensers.
- ↑ Despite being an occurrence of splashing, sculk sensors do not detect the sounds of fishing bobbers hooking a fish; this has been confirmed by Mojang to be intentional.[2]
- ↑ Milk does not trigger any vibration, and honey and stews trigger the eating event. See MC-213937
- ↑ Honey bottles and stews count as food for this case.
- ↑ This includes placing fire with flint and steel or a fire charge, and blocks placed by a dispenser or enderman
- ↑ Using fish buckets to breed axolotls does not cause this vibration. This inconsistency is intentional.[5]
- ↑ Replacing an existing fluid, in and out of a cauldron, does not trigger the event. See MC-213965.
- ↑ This does not include blocks broken by flowing water (MC-207410), nor redstone dust, redstone repeaters, redstone comparators or any type of rail being broken due to its supporting block being removed (MC-207411), nor the last slice of cake being eaten (MC-213968).

Issues
Issues relating to "Sculk Sensor" are maintained on the bug tracker. Report issues there.
Trivia
Recreated possible model of Calibrated Sculk Sensor.
Second variant recreate possible model of Calibrated Sculk Sensor.
- "Sculk" is derived from "skulk," meaning "keep out of sight, typically with a sinister or cowardly motive".[8]
There are two unused textures, "calibrated_sculk_sensor_top.png" and "calibrated_sculk_sensor_side.png", added in 20w49a. These are derivatives of the block of amethyst texture, potentially implying a planned connection; these could however be placeholder textures.- The textures in Bedrock Edition are still the old ones from development.
