Use the Moon Phase Detector for Redstone Contraptions

Automate with Moon Phases

The Moon Phase Detector is a redstone component that outputs a signal strength matching the current moon phase. This lets you create contraptions that respond to the lunar cycle.

How It Works

Place the Moon Phase Detector anywhere in the world. It will automatically emit redstone power based on the moon's current shape:

• Full moon = maximum signal strength
• New moon = no signal
• Waxing and waning phases = intermediate signal levels

Connect the detector to redstone dust, repeaters, comparators, or other redstone components to trigger doors, lights, farms, or other mechanisms.

Practical Uses

• Lunar farms: Activate crop lighting or harvesting systems only during full moons
• Themed builds: Create atmospheric lighting that changes with moon phases
• Logic gates: Use comparators to detect specific phases and trigger precise actions
• Decorative effects: Sync particle effects, note blocks, or mob spawners to lunar cycles

Pair the Moon Phase Detector with the Moon Dial item to plan ahead and know which phase is coming next.
