Sensors are essential components of mechanical beings, especially Transformers, serving a wide variety of functions and feeding a mechanoid information about the environment around it. Most Transformers are built with a set of standard senses - optic, audio, olfactory, tactile, short-range radio-wave transmission, electrical sensitivity and magnetic sensitivity are common in some universes - but many have specialized sensor packages that are unique or rare, giving them special abilities that make them stand out.
