15. The Armor Stand Pressure Plate Sensor
What This Idea Means
An Armor Stand placed precisely on the boundary line of a wooden pressure plate can be subtly nudged to trigger redstone signals through solid walls. By shifting or interacting with an decorative armor stand on display, you can trigger a hidden mechanism without exposing redstone wiring.
Materials Needed
- 1 Armor Stand
- 1 Wooden Pressure Plate
- 1 Piston
- Redstone Dust
- Sticky Pistons (for hidden door)
Step-by-Step Tutorial: How to Make It
- Set Sensor Floor: Dig a 2-block deep hole in the wall corner where you want your armor stand display. Place a pressure plate at the bottom.
- Place Armor Stand: Drop an armor stand onto the edge of the pressure plate.
- Wall Enclosure: Use a piston to gently push a solid decorative wall block over the lower half of the armor stand space so the plate is completely hidden inside the wall geometry.
- Wire Signal: Connect the pressure plate signal underneath the floor to your hidden door’s piston circuit.
- Trigger: Walk up to the armor stand and interact with it or bump slightly against its hit-box to trigger the plate beneath and open the door.
Tips and Variations
- Custom Armor Display: Dress the armor stand in Netherite armor or decorative mob heads so it looks like an ordinary armor display pedestal.
