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.
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).
