Relay Light Controlled Module tv-b-gone It describes how the LEDAutomatic Dusk to Dawn Switching Without a Microcontroller The Relay Light Controlled Module combines a light sensor and a relay on one board, so it can switch a load when the surrounding light level changes. That means you can build simple dusk to dawn or light triggered systems without adding a separate microcontroller. It is a useful module for outdoor lights, night indicators, greenhouse controls, and energy saving projects that need automatic
