A sprinkler that automatically pumps water from the ground and waters the surrounding fields.
This device can, for example, turn lights or sprinklers on and off depending on time and weather. For example: Connect your lamps on one side and the power source on the other side. Then connect a day/night sensor in the middle that opens and closes the energy circuit when it turns on/off. If you want the lights on during the day instead of at night, use the button to invert the input signal.
