Electric eye
A electric eye is a device made up of a photosensitive Capteur, whose Electrical resistance varies when it is subjected to a Rayonnement luminous (a such Photorésistance) and from an electrical circuit. The importance of the variation of resistance of photoresistance being proportional to the intensity of the light radiation, the electric eye can make it possible to measure an luminous intensity or to actuate various devices (automatic lighting, blind, electric shutter, etc).
