Sensors

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.

Audio sensors
Audio Sensors are a component of Transformer anatomy that allows them to hear sounds in their environment. Some are more acute than others, allowing recording of normally inaudible frequencies.

As part of a demonstration of the Dinobots, Blaster transformed into his alternate form allowing Grimlock to practice his fine tuned laser breath to start up Blaster's music. Ironhide told Blaster to stop the music as it was so loud that it was fusing his audio sensors.

Later, Blaster sent the Autobots the music from the rock concert that he, Spike Witwicky, and Carly were attending. Jazz was the only one who seemed to enjoy it, whereas Optimus and the others were nearly overcome in pain.

Equilibrium sensors
Equilibrium sensors help a Transformer keep their sense of balance.

Olfactory sensors
Olfactory sensors are a sensor unit used to detect the scents of others. It is very common in animal based Transformers. Ravage possessed one of the most powerful olfactory sensors. Transformers: The Ultimate Guide

Optical sensors
The optics on a Transformer mostly seem to perform in an identical way to human eyes, including all the flaws, such as the ability to be dazzled by bright light sources pointed directly at them. Atmospheres with a high particle content may require windshield wipers to keep optic sensors clear.

While all Transformers can usually be assumed to see in the same visual spectrum of colours than humans see in, there are exceptions who are completely colour-blind, and some Transformers demonstrate different perceptions (usually wherever the plot calls for it). Wreck-Gar, for instance, has 'magnetic vision,' probably quite useful given the uniform reddish hue of his home planet of Junkion!

Optical sensors typically came in visored and non-visored varieties. Sometimes on the same character.

There are also some of the Transformers possessed of Optic weaponry.

How Transformers "see" in their alternate forms has only been briefly touched on, however. In one story, it is explained that Transformers have some form of a linked visual network throughout their alternate form, whereas in other cases everyone is just drawn with big googly eyes inside their vehicle-mode headlights.

Targeting sensors
Targeting sensors are sensors which help a Transformer locate and identify a hostile entity.

Surveillance packages
Many Transformers possess sensor packages that allow them to record surveillance data for later review. Laserbeak in particular often serves in this function for the Decepticons.
