WebThe function of a photoelectric sensor is to use light to detect the presence or absence of an object. A photoelectric sensor consists of the sensor, control unit, and output. The source is a light-emitting diode that emits a powerful beam of infrared or visible light. WebTo wire your new light fixture, use your pliers to cut about 3/8" of insulation away from the wires. Twist together the black wire of the light fixture and the black wire of your house. Cover the new connection with a wire nut and make sure it is tight. Do the same thing with the white wires.

http://cord01.arcusapp.globalscape.com/how+does+night+vision+work+research+paper A self-contained photoelectric sensor contains the optics, along with the electronics. It requires only a power source. The sensor performs its own modulation, demodulation, amplification, and output switching. Some self-contained sensors provide such options as built-in control timers or counters. Because of technological progress, self-contained photoelectric sensors have become increasingly smaller. culture of maharashtra wikipedia
