Sensor/Legends

A sensor is one of any of a range of complex devices that enhance something's ability to receive data about its environment. Depending on the sensor, they can detect and analyze many forms of data, such as electromagnetic radiation, sound and vibration, gravity, nuclear radiation, magnetic fields, heat, pressure, trace chemicals, or the emissions of other sensors.

Sensors come in a variety of types. Some of the more common types include electro photo receptors, full-spectrum transceivers, dedicated energy receptors, and life form indicators. Rarer types include crystal gravfeld traps and hyperwave signal interceptors.

Sensors are, of course, not perfect. Not only can they fail to detect what they should or present false "ghost" images, they can be interfered with by natural phenomena like solar radiation, hydrogen clouds, asteroid fields, and potent gravity wells; and by artificial phenomena such as sensor jammers, sensor decoys, shield camouflage, stealth technology, and, of course, cloaking devices.
