How does calibrated sensor work in Minecraft? Explained

The calibrated sculk sensor is a relatively new block that was added by Mojang Studios in the Minecraft 1.20 Trails and Tales update. This is a variant of sculk sensor block that players can actually control, particularly in terms of which frequency it can detect and activate accordingly. This block is quite interesting and can allow players to create all kinds of semi-wireless redstone contraptions.

Here is a detailed guide to how the calibrated sculk sensor is made and used in Minecraft.

Calibrated sculk sensor in Minecraft: How to craft and use it

Calibrated sculk sensors do not generate naturally in Minecraft and can only be obtained by crafting them.

To craft this block, players will first need to head to a deep dark biome and get a sculk sensor from it. Next, they need to find an amethyst geode and get three amethyst shards from it.

The sculk sensor can be placed in the middle of the crafting table, while all three amethyst shards can be placed around it. The above picture can be referred to as the crafting recipe.

As mentioned above, a calibrated sculk sensor is quite different from a regular sculk sensor in Minecraft. As the name suggests, this sensor can be calibrated as per a player's needs.

Here are some of the key features of the calibrated sculk sensor:

• It can detect vibrations within a distance of 16 blocks.
• It can be activated for 10 game ticks after detecting a vibration.
• Several frequencies can be filtered so that it only reacts to some sounds.

A calibrated sculk sensor that detects vibrations is triggered for 10 game ticks and then must wait for 10 game ticks to detect another vibration. This means that, in contrast to a standard sculk sensor, which can detect vibrations once every two seconds, a calibrated sculk sensor can detect vibrations every second.

Once players craft a calibrated sculk sensor, they can place it and use it in any redstone contraption in Minecraft. The block allows players to select only one vibration frequency that they want it to detect. The frequency filtering can be done by sending a redstone signal through a block that can send almost all signals from one to 15.

On the crystalized side of the calibrated sculk sensor, players can place a redstone block that can send signals as input.

To filter the frequencies that the block senses, for instance, lecterns with books on them and redstone comparators can be installed. A specific redstone signal will be transmitted to the block based on which page of the book is open on the lectern. It will therefore be able to detect that particular vibration only.

Since the game has 15 different signals of redstone, Mojang Studios made 15 calibrated sculk sensor frequencies as well and linked them with signals.

Here is a list of which activities come under which frequencies:

• Redstone Signal/Frequency 1 - Walking, climbing, jumping, swimming, crawling
• Redstone Signal/Frequency 2 - Landing on any solid block, or in any liquid
• Redstone Signal/Frequency 3 - Using an item
• Redstone Signal/Frequency 4 - Player gliding with an elytra or a mob performing a unique action
• Redstone Signal/Frequency 5 - Dismountin a mob or equipping a gear
• Redstone Signal/Frequency 6 - Mounting a mob or interacting with a mob
• Redstone Signal/Frequency 7 - A mob or a player taking damage
• Redstone Signal/Frequency 8 - Eating food items
• Redstone Signal/Frequency 9 - A block getting deactivated
• Redstone Signal/Frequency 10 - A block getting activated
• Redstone Signal/Frequency 11 - A block changing its state
• Redstone Signal/Frequency 12 - A non-wool block being destroyed
• Redstone Signal/Frequency 13 - A non-wool block being placed
• Redstone Signal/Frequency 14 - A player or a mob teleporting or spawning
• Redstone Signal/Frequency 15 - A player or a mob dying, or an explosion

Fixing a calibrated sensor on a particular frequency using a lectern means that it will only detect sounds that are on that level of frequency and ignore everything. This way, it can be used to create redstone contraptions that only get activated when a certain activity is performed.
