Sensors detect aspects of the physical world—matter, energy, force—in much the same way as a person’s or animal’s senses. But instead of translating the information into nerve impulses, sensors translate them into electrical signals that can be stored, processed by a computer, or displayed on a screen. They can be a current or voltage that is constant or varying with time.
