The sensor array gives you a way to determine your enemy's hull strength, shield strength and if applicable, armour strength.

Wire inputs/outputs It has one wire input, the target entity you want information about. If you target a ship core, you'll get the whole ship's health and its shield generator's status too if it has one.

As for outputs, it depends on what you wired as the target.

   Health - The amount of hull strength the target has.
   Max Health - The maximum hull strength the target has.
   Plating - For a ship core, this is the plating amount. Ranges from 0 to 100.
   Shields - For a shuttle, this is the shuttle's current shield strength. Ranges from 0 to 100.
   Armour - For a type 11/class 2 shuttle (or a mod+'s ship core) this is the current armour health.
   Shield Emitter - If your target is a ship core with a starship shield, then this is its total charge.
   Shield Active - 1 if your target's starship shield is raised, 0 otherwise.
