Din Rail light sensor relay
Twilight switch with external fotosensor that goes on din rail. Used for switching lights, illumination of advertisements, shop windows, etc. I ordered this from aliexpress, the reference link is down below. The project that I use this for is time and light switch for my facade lights. I also need to buy a junction box with din relay and time switch for din relay. Using light sensor I switch the light on when it's dark outside and with time relay I switch the lights off from 12 at night to 8 in the morning to save electricity.
