Controls the ignition of lamps or other electrical loads when the brightness of the environment falls below an adjustable threshold.
There are circuits that never get old and withstand time, progress, and emergence and spread of a variety of microcontrollers and boards, perhaps because there is always a need of something simple, cheap and that gets the job done.
Among those there’s the twilight switch, that will never get old, at least until  there will be the need for something to turn the lights on and off based on ambient light.

We propose a project that, despite being a classic, adapts to one of the needs of modern times: miniaturization. In fact, what we present is a magnificent twilight switch a with relay output to control in low voltage loads (to handle loads operating at 220 VAC just use an  adequate capacity relay to control the exchange) whose printed circuit board, complete with all components, measures just 29x29x15 mm!

This project comes in kit. Some components have to be soldered to the included PCB.
