Optical attenuators are commonly used in, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels.

The Lightseeking sensor Module can be used on a smart car robot for the experiment about light seeking. The basic principle of the infrared sensor is to use the reflective nature of the object. Since the resistance of a photoresistor decreases with stronger light, the car can be controlled to move based on the resistance change, that is, to seek for the light and follow it. Hyperion, an experimental robot, was developed by roboticists at the Robotics Institute at Pittsburgh's Carnegie Mellon University, CMU. For a better understanding, have a look at the line following robot, surveillance robot car, obstacle-avoiding robot t hat. Light Sensors are photoelectric devices that convert light energy (photons) whether visible or infra-red light into an electrical (electrons) signal What Are Light Sensors? A Light Sensor generates an output signal indicating the intensity of light by measuring the radiant energy that exists in a.

The major purpose of lightning protection systems is to conduct the high current lightning discharges safely into the Earth/ground. For example, it will not only affect all DWDM fiber channels in short bursts, but also affect transmission directions. It is the magnitude of the current during lightning strikes and the consequences of its impact on objects that have always attracted the at-tention of researchers, while the other characteristics of lightning have received less attention.
