Sensor refers to any kind of equipment and technology which is used to measure, record, and detect the environment of time and space.
Sensors can range from a simple visual recording device to technologies which can analyze and detect occurrences in and out of the spectrum of the universe.
Long-range subspace sensor capability required the technology of the transtator. (TOS comic: "Prisoners")
Handheld sensors[]
Early handheld sensors took on the form of scanners which had limited abilities and range. By the 23rd century Starfleet used tricorders, a far more advanced sensor technology; there were also specialist tricorders for medical scans.
In addition to general purpose handheld devices, there are hand held detectors and scanners for a variety of specific detection and measuring requirements.
Starship and facility sensors[]
Starships generally have much more powerful sensors, capable of detecting a wide range of phenomenon from a great distance. If a single starship is insufficient, groups of ships can be used, as was the case when the first tachyon detection grids were developed to detect cloaked ships. (TNG episode: "Redemption")
