Importance of Redstone Comparators
Redstone comparators are essential for advanced Redstone builds because they can perform several functions:
- Signal Comparison: They compare the strength of two Redstone signals.
- Signal Subtraction: They subtract one signal strength from another.
- Content Detection: They measure the fullness of containers and the states of certain blocks.
Understanding how to craft and use Redstone comparators is key to creating more complex and efficient Redstone contraptions in Minecraft. For more detailed comparisons and guides, visit COMPARE.EDU.VN.
2. What is the Function of a Redstone Comparator?
The primary function of a Redstone comparator is to manipulate Redstone signals based on input signal strengths and the comparator’s mode. It can compare signal strengths, subtract signals, and measure the contents of containers or states of specific blocks.
Redstone comparators have three main functions:
-
Signal Comparison:
- The comparator compares the signal strength from its main input to the signal strength from its side input.
- If the main input is stronger than the side input, the comparator outputs the main input’s signal strength.
- If the side input is stronger, the comparator outputs no signal.
-
Signal Subtraction:
- In subtraction mode (activated by right-clicking the comparator), the comparator subtracts the side input’s signal strength from the main input’s signal strength.
- The resulting difference is the output signal strength. If the side input is greater than the main input, the output is zero.
-
Content Detection:
- The comparator can measure the fullness of containers (like chests, hoppers, and furnaces) and output a Redstone signal strength proportional to the container’s fullness.
- It can also detect the states of certain blocks, such as the number of eyes of Ender in an end portal frame or the charge level of a respawn anchor.
Practical Applications
Redstone comparators are used in various Redstone builds, including:
- Item Sorters: Sorting items into specific containers based on their type.
- Automatic Farms: Detecting when crops are ready for harvest.
- Logic Gates: Creating complex logic circuits for automated systems.
- Fuel Level Indicators: Monitoring the fuel level in furnaces or other fuel-consuming devices.
Comparator Modes
The comparator has two modes, indicated by the state of the front Redstone torch:
- Comparison Mode: The front torch is off, and the comparator compares signal strengths.
- Subtraction Mode: The front torch is on, and the comparator subtracts signal strengths.
To switch between modes, simply right-click on the comparator.
Advanced Uses
Comparators can also be used to read data from blocks like lecterns (to determine the page number of an open book) and jukeboxes (to determine which disc is playing). These advanced uses make comparators invaluable for creating intricate and intelligent Redstone systems.
For more information on Redstone comparators and their uses, check out detailed guides and comparisons at COMPARE.EDU.VN.
3. How Does a Redstone Comparator Compare Inputs?
A Redstone comparator compares the signal strength of its main input to that of its side input. In comparison mode, if the main input is stronger, the comparator outputs that signal strength. If the side input is stronger or equal, the comparator outputs no signal.
The Redstone comparator has three terminals:
- Main Input: Located at the back of the comparator.
- Side Inputs: Located on the left and right sides of the comparator.
- Output: Located at the front of the comparator.
Signal Strength
Redstone signal strength ranges from 0 to 15, where 15 is the strongest signal. A Redstone source (like a lever or Redstone block) emits a signal strength of 15, which decreases by 1 for each block the Redstone wire travels.
Comparison Mode
In comparison mode (the default mode, with the front torch off):
- The comparator measures the signal strength of the main input.
- It measures the signal strength of the strongest side input (only one side input is considered).
- If the main input’s signal strength is greater than the side input’s signal strength, the comparator outputs the main input’s signal strength.
- If the side input’s signal strength is greater than or equal to the main input’s signal strength, the comparator outputs no signal (signal strength of 0).
Example
- If the main input has a signal strength of 10 and the side input has a signal strength of 7, the comparator outputs a signal strength of 10.
- If the main input has a signal strength of 5 and the side input has a signal strength of 8, the comparator outputs a signal strength of 0.
Practical Applications
Signal comparison is useful for:
- Priority Systems: Ensuring one signal takes precedence over another.
- Threshold Detection: Activating a circuit only when the main signal is above a certain strength.
- Security Systems: Triggering alarms when an unauthorized signal interferes with the main signal.
For example, in a security system, the main input could be a Redstone signal from a pressure plate inside a base, and the side input could be a signal from outside the base. If someone tries to bypass the pressure plate by sending a Redstone signal from outside, the comparator will detect that the side input is stronger and cut off the main signal, triggering an alarm.

4. How to Use Redstone Comparator in Subtraction Mode?
In subtraction mode, a Redstone comparator subtracts the signal strength of its side input from its main input, outputting the difference. If the side input is stronger than the main input, the output is zero.
To use a Redstone comparator in subtraction mode:
- Place the Comparator: Place the Redstone comparator where you need it in your circuit.
- Activate Subtraction Mode: Right-click (or use the appropriate action button on your device) on the comparator. The front Redstone torch will light up, indicating that the comparator is in subtraction mode.
- Connect the Inputs: Connect the main input to the back of the comparator and the side input to either the left or right side.
Subtraction Process
In subtraction mode:
- The comparator measures the signal strength of the main input.
- It measures the signal strength of the strongest side input.
- It subtracts the side input’s signal strength from the main input’s signal strength.
- The resulting difference is the output signal strength. If the side input is greater than the main input, the output is zero.
Example
- If the main input has a signal strength of 15 and the side input has a signal strength of 6, the comparator outputs a signal strength of 9 (15 – 6 = 9).
- If the main input has a signal strength of 4 and the side input has a signal strength of 10, the comparator outputs a signal strength of 0 because the side input is stronger.
Practical Applications
Subtraction mode is useful for:
- Logic Gates: Creating AND and XOR logic gates.
- Proportional Control: Adjusting an output signal based on the difference between two input signals.
- Fuel Gauges: Measuring the amount of fuel remaining in a furnace or other fuel-consuming device.
For example, in a fuel gauge, the main input could be connected to a container holding fuel, and the side input could be connected to a mechanism that reduces the signal strength as fuel is consumed. The comparator would output a signal strength that represents the amount of fuel remaining.
Advanced Techniques
Subtraction mode can be combined with other Redstone components to create complex and efficient circuits. Experiment with different input signal strengths and comparator placements to achieve the desired results.

5. What is Measured by a Redstone Comparator?
A Redstone comparator can measure the fullness of containers, the state of certain blocks, and the strength of Redstone signals. These measurements are then converted into a Redstone signal strength output.
The Redstone comparator can measure:
-
Container Fullness:
- Chests, hoppers, furnaces, and other containers.
- The comparator outputs a signal strength proportional to how full the container is.
-
Special Block States:
- End portal frames (whether they contain an eye of Ender).
- Item frames (the rotation of the item inside).
- Jukeboxes (which disc is playing).
- Lecterns (the page number of the open book).
- Respawn anchors (the charge level).
-
Redstone Signal Strength:
- The strength of Redstone signals from its main and side inputs.
Container Measurements
When measuring containers, the comparator outputs a signal strength based on the percentage of filled slots. The more items in the container, the stronger the signal.
- Empty Container: Signal strength of 0.
- Full Container: Signal strength of 15.
Special Block Measurements
The signal strength output for special blocks varies:
- End Portal Frame: 0 if empty, 15 if an eye of Ender is inserted.
- Item Frame: 1-8 depending on the rotation of the item.
- Jukebox: 1-14 depending on the disc being played.
- Lectern: 1-15 depending on the page number of the open book.
- Respawn Anchor: 0, 3, 7, 11, or 15 depending on the charge level (0-4 charges).
Redstone Signal Measurements
The comparator measures the signal strength of Redstone signals from its main and side inputs, which can then be compared or subtracted based on the comparator’s mode.
Practical Applications
These measurements are used in various Redstone contraptions:
- Item Sorting: Detecting when a container is full to redirect items.
- Automated Farms: Monitoring crop growth or animal population.
- Game Shows: Creating interactive elements based on player actions.
- Security Systems: Detecting unauthorized access or changes in the environment.

6. How Redstone Comparators Work with Containers?
Redstone comparators can detect the fullness of containers such as chests, hoppers, and furnaces, converting this information into a Redstone signal strength. The more items in the container, the stronger the output signal.
The comparator reads the fullness of a container by:
- Detecting Occupied Slots: The comparator checks how many slots in the container are occupied.
- Calculating Percentage: It calculates the percentage of slots that are filled.
- Converting to Signal Strength: The percentage is converted into a Redstone signal strength ranging from 0 to 15.
Container Types
Different container types have different numbers of slots:
- Chests: Small chests have 27 slots, while large chests have 54 slots.
- Hoppers: Have 5 slots.
- Furnaces: Have 3 slots (input, fuel, output).
- Barrels: Have 27 slots.
- Shulker Boxes: Have 27 slots.
The signal strength output by the comparator depends on the container type and how many slots are filled. For example, a chest with 27 items will output a lower signal strength than a hopper with 3 items.
Signal Strength Calculation
The formula for calculating the signal strength is:
Signal Strength = Floor( (Number of Filled Slots / Total Number of Slots) * 14 ) + (Number of Filled Slots > 0 ? 1 : 0)
Examples
- A chest with 0 items: Signal strength of 0.
- A chest with 27 items: Signal strength of 7.
- A chest with 54 items (full): Signal strength of 15.
- A hopper with 0 items: Signal strength of 0.
- A hopper with 5 items (full): Signal strength of 15.
Practical Applications
Using comparators with containers has many practical applications:
- Item Sorters: Sorting items into specific containers based on their type.
- Automatic Farms: Detecting when crops are ready for harvest and automatically collecting them.
- Storage Systems: Monitoring the amount of items stored and triggering alerts when containers are full or empty.
- Fuel Management: Monitoring the fuel level in furnaces and automatically adding more fuel when needed.
Advanced Techniques
Comparators can be combined with other Redstone components to create complex and efficient storage and automation systems. Experiment with different container types and comparator placements to achieve the desired results.
