Sculk Sensor

A sculk sensor is a sculk block that detects vibrations caused by nearby actions and events and emits a redstone signal in response. Player-caused vibrations can also trigger nearby sculk shriekers. Sneaking prevents the creation of vibrations while moving, and wool can be used to block or prevent them. Placing an amethyst block next to a sculk sensor allows it to "relay" detected vibrations to other sculk sensors.
