Sensors

Sensors is a device that responds to a physical stimulus that may be as heat, light, sound, pressure, magnetism, or a particular motion and transmits a resulting impulse as for measurement or operating a control.

Devices that transform (or transduce) physical quantities such as pressure or acceleration (called measurands) into output signals (usually electrical) that serve as inputs for control systems.Some of the characteristics of the device that make it suitable for a multiple range of applications are its small size, ability to function without electrical power (making it convenient to be used at remote places), ability to be multiplexed along the length of the fibers, ability to sense time delay as light passes through each sensor etc.
