Heavy Weighted Pressure Plate

A heavy weighted pressure plate is a type of pressure plate that produces a redstone signal while one or more entities stand on it. Depending on how many entities are detected, the outputted signal strength will range from 1 to 15.

A heavy weighted pressure plate can be mined with anything, but pickaxes are the fastest. A heavy weighted pressure plate also breaks and drops itself if a piston extends or pushes a block into its location, or if the block under the pressure plate is moved or destroyed.

Heavy weighted pressure plates can be activated by most entities (including players, mobs, items, arrows, experience orbs, fishing bobs, etc.) and emit a redstone signal strength that is equal to 1⁄10 (rounded up) of the amount of entities on top of them, up to a maximum power level of 15. Certain entities, however (such as players in spectator mode and markers), cannot activate them nor keep them activated.
