Weighted Pressure Plate
A weighted pressure plate is a block similar in function to regular pressure plates, except it outputs a varying redstone signal strength depending on the number of objects on it. The weighted pressure plate comes in 2 variants, a light version (gold) and a heavy version (iron).
The light version emits a stronger redstone current for every entity upon it. It reaches maximum signal when it has 15 entities upon it.
The heavy version emits a stronger redstone current for every 10 entities upon it, rounded up. It reaches maximum signal when it has 141 entities upon it.
Both mobs and dropped items trigger weighted pressure plates, though only distinct item entities will count separately - for example, dropping 3 cobblestone on a gold pressure plate will briefly output a signal strength of 3, but the signal will quickly drop down to 1 when the three items are merged.
The following table will show how many mobs/items should be on pressure plate to output a signal of certain strength:
|Gold plate||Iron plate|
Weighted Pressure Plate (Heavy)
Weighted Pressure Plate (Light)
|1.5||13w01a||Added weighted pressure plates.|
|1.7.2||13w36a||Weighted Pressure Plates now output a signal relative to the amount of entities on them (including both mobs and items), always starting at 1 signal strength if any entities are present|
|For Light Weighted Pressure Plates, every entity adds 1 strength to the signal|
|For Heavy Weighted Pressure Plates, starting at 1, every 10 entities adds 1 strength to the signal (Example: 11 entities increases signal strength to 2)|

Issues relating to "Weighted Pressure Plate" are maintained on the issue tracker. Report issues there.
- The pressure plates have the texture of iron and gold blocks. This is most noticeable with the 4 stripes on the iron pressure plate.
- They are also able to be put on fences and can be used as a fake gold/iron block.
- The density of gold is nearly two and a half times that of iron, yet it is used to craft the Light Weighted Pressure Plate. However "Light" does not refer to the weight of the plate itself, but how much additional weight is required to get the maximum current.
- Wooden Pressure Plates are triggered by a single item, effectively making them Very Light Weighted Pressure Plates.
