Sculk sensors pass on the vibrations made by players to sculk shriekers within 8 blocks of the sensor. When walking or jumping on the edge of a wool block, the player's center has to be over the wool, otherwise the vibration may be detected. 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). While sneaking, a player is not detected when walking, falling, dropping items, or shooting a projectile. 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.
