Uncle Jeff's Sensors: Expanding Redstone Possibilities
Vanilla Minecraft offers a solid foundation for redstone engineering, but seasoned builders often hit a ceiling when they need environmental awareness or entity-specific detection. Standard pressure plates cannot tell a villager from a zombie, and daylight sensors only track the sun. Uncle Jeff's Sensors: Expanding Redstone Possibilities shatters that ceiling by introducing a suite of specialized detection blocks that integrate seamlessly with existing redstone logic. This add-on transforms how you approach automation, security, and resource management, giving you tools that respond to lunar cycles, local weather, and even specific mob types.
What This Add-On Brings to Your World
Uncle Jeff's Sensors: Expanding Redstone Possibilities is not a single block but a family of interconnected devices. The mod is designed for players who want granular control over their contraptions without resorting to complex command blocks or bulky observer chains. It supports modern Minecraft versions and runs on both Forge and NeoForge loaders, ensuring broad compatibility with your existing modpack. The add-on has evolved from a simple moon phase detector into a comprehensive toolkit, and each component serves a distinct purpose in your automation arsenal.
Lunar Sensor: Timing Your Builds to the Night Sky
The lunar sensor operates on a principle similar to the vanilla daylight detector but reads the moon instead of the sun. It outputs a redstone signal strength that corresponds to the current phase of the eight-day lunar cycle. At night, the signal equals the phase number plus one, while during the day it drops to zero. This allows you to trigger mechanisms only on specific nights, enabling schedules that repeat weekly in game time.
The crafting recipe is deliberately unconventional to prevent conflicts with other mods that might use similar ingredients. In a 3x3 crafting grid, arrange three glass blocks across the top row. In the middle row, place a red mushroom, a quartz slab, and a raw cod (not clownfish, pufferfish, or salmon). The bottom row requires any wooden slab, redstone dust, and another wooden slab. This unusual combination ensures that the recipe remains unique across various modpacks.
Signal outputs by phase are as follows:
- Full moon: signal strength 1
- Waning gibbous: 2
- Last quarter: 3
- Waning crescent: 4
- New moon: 5
- Waxing crescent: 6
- First quarter: 7
- Waxing gibbous: 8
Pairing the lunar sensor with a daylight detector unlocks creative timing solutions. For instance, you can program a minecart with chest to travel a circular track, stopping at multiple loading and unloading stations only during twilight transitions when both sensors briefly activate. This creates a fully automated delivery system that runs on a predictable schedule without player intervention.
Weather Sensor: Reading the Skies for Automation
The weather sensor resembles a pale cauldron and emits a signal whose strength depends on the current local weather conditions. It accounts for the biome you are in, making it a versatile tool for environmental monitoring. In deserts, cloud cover produces a signal of 1. In snowy regions, snowfall generates signals from 1 to 5. Rain yields signals between 6 and 10, while thunderstorms push the output to 11 through 15. The device only functions outdoors and above ground; placing it indoors or underground renders it inert. The water level visible inside the sensor is purely decorative and cannot be collected.
Crafting the weather sensor requires a quartz slab, an iron ingot, and another quartz slab across the top row. The middle row uses three quartz slabs, and the bottom row consists of netherrack, redstone dust, and netherrack. This recipe is straightforward and uses materials readily available after a trip to the Nether.
For players seeking a streamlined experience, you can download Uncle Jeff's Sensors: Expanding Redstone Possibilities through popular launchers that support mod management. The installation process is simplified, and updates are tracked automatically, keeping your version current. The weather sensor proves invaluable for farms that depend on rain, such as automatic crop irrigation systems, or for server-wide alert systems that notify players when a thunderstorm approaches.
Smart Pressure Plates: Entity-Specific Detection
Starting with Minecraft 1.8, the mod introduced a family of specialized pressure plates. Each plate responds only to a specific category of creatures, outputting a signal based on the strength of the detected mob. If multiple qualifying entities stand on the plate simultaneously, the signal reflects the most powerful one. All plates share a common 2x2 crafting pattern: two key ingredients on top and two redstone dust below. Crafting any plate for the first time grants an advancement, but only if you craft it by dragging the item rather than using shift-click.
Person Detector
The key ingredient for this plate is a hay bale. It reacts to non-hostile humanoids. Signal outputs are: zombie pigman at strength 1, villager at strength 2, and player at strength 15. This plate is ideal for creating private entrances that only you and trusted villagers can use, or for triggering traps when an intruder steps on it.
Livestock Detector
Using a clay block as the key, this plate detects farm animals. Chicken produces a signal of 1, pig 2, cow 3, sheep 4, rabbit 5, squid 6, and mooshroom 7. The killer rabbit variant does not activate this plate, keeping your livestock systems safe from accidental triggers. This plate simplifies sorting systems on animal farms, allowing you to separate different species without complex redstone logic.
Wild Animal Detector
The brick block serves as the key ingredient. This plate responds to passive wild creatures: bat at signal 1, horse at 2, wolf or tamed dog at 3, and ocelot or tamed cat at 4. Use this to build wildlife monitoring stations or to create safe zones that detect approaching predators.
Monster Detector
Mossy cobblestone is the key. This plate covers a wide range of hostile mobs: slime or magma cube at 1, zombie at 2, skeleton or wither skeleton at 3, spider at 4, creeper at 5, silverfish at 6, witch at 7, killer rabbit at 8, and enderman at 9. The distinct signal levels allow you to differentiate between threats, enabling sophisticated defense systems that respond differently to each mob type.
Demon Detector
Quartz ore acts as the key. This plate focuses on Nether creatures: magma cube at 1, ghast at 2, skeleton at 3, wither skeleton at 4, and blaze at 5. Combining this with the monster detector lets you sort mobs from the Nether and the Overworld into separate processing streams, which is perfect for mob farm optimization.
Owner Detector
The crafting table is the key ingredient. This plate emits a signal of 15 when the player who placed it stands on it. You can invert the logic to react to everyone else, creating a secure lock that only you can bypass. This is particularly useful for personal storage rooms or hidden bases.
Practical Applications and Build Ideas
Uncle Jeff's Sensors: Expanding Redstone Possibilities shines when you combine its components. A monster detector paired with a demon detector can separate hostile mobs from different dimensions, routing them to distinct kill chambers or storage systems. The livestock detector simplifies animal husbandry by automatically opening gates for specific species. The owner detector provides a simple yet effective security layer for multiplayer servers.
For advanced builders, the lunar and weather sensors open up time-based automation. You can schedule a cobblestone generator to activate only during thunderstorms, or program a beacon to power up during full moons. The possibilities are limited only by your imagination.
Installation and Compatibility
To get started, you need to download Uncle Jeff's Sensors: Expanding Redstone Possibilities for Minecraft from a trusted source. The mod supports recent game versions and is compatible with both Forge and NeoForge. Before installing, ensure you have the correct loader version for your Minecraft client. Place the downloaded JAR file into your mods folder, then launch the game.
