Calibrated Sculk Sensor

This article is a work in progress.

Please help in the expansion or creation of this article by expanding or improving it. The talk page may contain suggestions.

This article describes content that may be included in Java Edition and Bedrock Edition.

This content has appeared in Java Edition 1.20 and Bedrock Edition 1.19.80 development versions, but the full update containing it has not been released yet.

The features on this page are exclusive to Experimental Gameplay in Bedrock Edition.

These features may be properly added in a future update, but currently require enabling one or more settings in the "Next Major Update" section of the Game Settings menu.

A calibrated sculk sensor is a variant of the regular sculk sensor that allows to filter which vibration frequency it detects through a redstone signal input.

Breaking

Calibrated sculk sensors can be broken with any tool, but can be broken faster with a hoe. They drop experience when broken. When broken by an item that is enchanted with Silk Touch, a calibrated sculk sensor drops itself.

Usage

This section needs expansion.

You can help by expanding it.

Unlike the regular sculk sensors, there are a few differences:

Calibrated sculk sensor can detect vibrations up to 16 blocks away.

Calibrated sculk sensors have a cooldown of 1 second instead of 2 seconds.

One side of the calibrated sculk sensor can receive a redstone signal as an input, and the strength of that redstone signal is the only vibration frequency the sculk sensor will listen to. The following list showcases (in order) a list of frequencies that the calibrated sculk sensor can listen for.

Movement in any medium (land, water and air)
Landing on any surface (land or water)
Item interactions
Gliding with an elytra or unique mob actions (Ravager roar, Wolf shaking, etc)
Dismounting a mob or equipping gear
Mounting a mob or interacting with a mob
Mobs and players getting damaged
Consuming items (drinking and eating)
Blocks 'deactivating' (door close, chest close, button unpress, etc)
Blocks 'activating' (door open, chest open, button press, etc)
Blocks changing (adding food to campfire, etc)
Blocks being destroyed
Blocks being placed
Mobs and players teleporting or spawning
Mobs and players dying or an explosion

A way to set the frequency that a calibrated sculk sensor listens to is by placing a lectern with a 15-page written book inside it next to a redstone comparator connected to the calibrated sculk sensor and turning the page number to the specific frequency that is desired.

History

Java Edition
October 12, 2020		Brandon Pearce mentioned adding "habituation" to the skulk sensor.
1.17	20w49a	Added unused textures for calibrated sculk sensor to the game files (specifically to the `assets/minecraft/textures/blocks` directory).
		The top texture is a translucent version of the block of amethyst texture, where the side texture is composed of the sculk sensor's side texture overlayed on the amethyst texture.
		The amethyst textures are based on those from 20w45a, despite these textures being added after the amethyst block textures were redone twice, implying these textures come from a scrapped functionality of the sculk sensor coupled with amethyst.
	21w13a	Removed texture files from the game files.^[1]
Upcoming Java Edition
1.20	23w12a	Added calibrated sculk sensors.
	23w14a	Calibrated sculk sensors now detect vibrations up to 16 blocks radius instead of 8 blocks.
		Calibrated sculk sensors now have 1 second active cooldown instead of 2 seconds.
		Calibrated sculk sensors now accept signals into the calibration input side more consistently with other Redstone components.
		Calibrated sculk sensors can now be activated by sniffer digging.
		Calibrated sculk sensors can now glow when they trigger, just like a regular sculk sensor.
		Default redstone output has been modified to be more reliable for distance calculations.
		Calibrated sculk sensors can now strongly power the block they are placed on.
Upcoming Bedrock Edition
1.19.80	beta 1.19.80.22	Added calibrated sculk sensors.
