StormTrooper armor is just basicly a black skintight sock with a shell over it. No special sensors, just a shell with a comlink in the helm. We dun call em plasticmen in the game for nothing.
Taken from Star Wars Databank:
The soldiers of the Empire struck with frightening anonymity, their faces completely obscured by unmistakable white armor. While the 18-piece armored shell offers limited protection from blaster fire, it also serves as a weapon of terror.
The bone-white armor fits over a black temperature-control body glove. Built-in helmet comlinks supplemented by belt-mounted hand-held units ensure that stormtroopers are always in touch with their superiors. Standardized utility belts offer ammunition for blaster sidearms, and helpful tools such as grappling hooks and cable. Stormtrooper armor also serves as a limited space suit for protection against hard vacuum.
The Empire maintained a number of variant armor styles to fit different mission profiles. The armor of desert terrain units, cold assault divisions and scout squadrons are all slightly different.
Luke Skywalker and Han Solo took advantage of the faceless stormtrooper uniform when infiltrating the Death Star prior to the Battle of Yavin. They were able to surreptitiously enter the battle station's detention block to free a captive Princess Leia Organa.
