Detect Items and Trigger Redstone With Sensors

Placing a Sensor Attachment

Attach a Sensor to any pipe by right-clicking a pipe face with the attachment. Open the Sensor GUI to specify which items or fluids you want to detect.

Configuration

• Whitelist mode: Sensor outputs redstone when specified items pass through
• Blacklist mode: Sensor outputs redstone when anything *except* specified items passes through
• Fluid detection: Sensors can also detect specific liquids in fluid pipes

Practical Uses

Use sensors to:

• Trigger a hopper or dispenser when certain items arrive
• Activate a redstone lamp when your storage reaches a target item
• Control machines based on what's flowing through your pipes
• Create automated alerts when specific resources are being transported

Sensors output a redstone pulse, so pair them with redstone comparators or repeaters for more complex logic. Multiple sensors on the same pipe can trigger different devices independently.
