The Sculk Sensor is a unique block that will be added to Minecraft with the upcoming Caves and Cliffs update. It detects a plethora of sounds and emits a Redstone signal when activated.
The Sculk Sensor has a texture similar to The Warden, and its noise detection features are also similar.
The Sculk Sensor in Minecraft
The Sculk Sensor has a unique ability to detect noises (or vibrations).
While Sculk Sensors cannot be found in Minecraft right now (besides Creative inventory or using commands), these interesting blocks are slated to be found in the Deep Dark Caves biome along with The Warden.
Sounds such as walking, jumping, and eating within eight blocks of the Sculk Sensor will activate it, causing it to light up and move rapidly. Players who are crouching will not be detected when walking, jumping and shooting a projectile.
A visible wave will be seen coming from the source of the noise towards the sensor. Additionally, when a block of wool is between the sensor and the noise, the sensor will not be triggered (Java Edition only).
Once activated, the Sculk Sensor will emit a Redstone Signal and some noise. However, this noise does not trigger other Sculk Sensors.
The signal strength is determined by the distance that the noise is detected. If the detection is close, the signal is stronger. The farther the detection is, the weaker the Redstone signal becomes. Thus, the strongest Redstone signal can be produced by vibrations directly on top of the sensor.
Sculk Sensors can be waterlogged. They can detect noise when waterlogged. However, they will not emit the noise that is usually emitted.
