Twilight automaton with an internal AZH photosensitive sensor AZH

The twilight switch is used to automatically turn on the lighting of streets, squares, exhibitions, advertisements, etc. at dusk and turn off the lighting at dawn. If the length of the probe's connection cable exceeds 10 m, it should not be run close to the parallel cable under voltage. mains or carrying large currents. When checking the operation of the machine, cover the whole machine tightly, e.g. with a cardboard box or a dark, thick cloth. Covering only the "eye" probe, e.g. with a finger, is insufficient, because the intensity of sunlight is very strong and penetrates the photoelement through the plastic housing and the human body.
