This value can be measured with a comparator. 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.Įach vibration in the game falls under a certain amplitude value. Sculk sensors emit a redstone signal when they are activated. Alarms can be blocked by wool placed in between the sensor and shrieker, similar to how wool can block vibrations from reaching the sensor itself. For example, an item dropped by a player triggers the shrieker, but an item dropped by a dispenser or from a broken block does not a player flying around with elytra triggers the shrieker, but a bat flying around does not. Sculk sensors pass on the vibrations made by players to sculk shriekers within 8 blocks of the sensor. Sculk sensors are not able to detect footsteps or dropped items on wool blocks or carpet, and they are also unable to detect dropped items of wool and carpets. If the ray passes diagonally through the edge between two blocks, either one or the other block may muffle it but not both. Specifically, if the ray joining the cube centers of the sensor block and the vibration source passes through any wool blocks, the noise is muffled. If a wool block is placed between a sensor and a vibration source, the sensor is not able to detect the placed wool nor vibrations behind it. Wool and carpets have a special interaction with sculk sensors.

Sculk sensors don't detect vibrations from other sculk sources or the warden. This prevents them from activating when a contraption it is powering is being unpowered. During this short cooldown period, they cannot detect vibrations. Sculk sensors have a cooldown period of 1 game tick (0.05 seconds) after being placed or after deactivating. The sensor cannot detect any other vibrations while activated or while a signal is traveling to it. When the signal arrives, the sensor is activated for 40 game ticks (2 seconds). 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 block per game tick (20 blocks per second). Walking, falling, dropping items, or shooting a projectile all trigger the sensor. While sneaking, a player is not detected.

Vibrations are caused by various events, such as a player and mobs walking, placing or breaking blocks, gliding with elytra, items falling on the ground, a piston extending or a wet wolf shaking itself off. Sculk sensors detect vibrations in an 8 block spherical radius around it. When active, it changes to a lighter block state without a change to the light level.
