Detectors
Definition
Detectors are devices used to measure or detect various physical quantities such as light intensity, radiation levels, temperature, or electric current.
Analogy
Imagine detectors as your senses - just like how your eyes detect light or your skin detects temperature changes. Detectors act as specialized "senses" for scientists and engineers to gather information about different aspects of the world around us.
