detectors
Things that sense
Detectors are devices or instruments that sense and identify the presence of something—radiation, metal, smoke, motion, or other phenomena.
A smoke detector alerts to fire.
A metal detector finds buried coins or screens for weapons.
A lie detector monitors physiological responses during questioning.
The word also applies to people who detect: The customs officer was a skilled detector of contraband.
