Sculk Sensor

The sculk sensor is a block that can detect vibrations and emit a redstone signal.

Obtaining
Sculk Sensors can be obtained only from the creative inventory.

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. This means that the closer the vibration is, the stronger the redstone signal is. The output is also scaled based on the sculk sensor’s radius, so it can reach the max redstone signal strength when the vibration is 0 distance away (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. With the right contraption, this allows you to detect when a certain action has occurred nearby.

Wool Occlusion
Wool has a special interaction with sculk sensors. If a wool block is in the way of a vibration source, the sensor will not be able to detect it.
