(Kicad) pcb design for water level sensor xkc y25

[Sefanoulis7]

When the sensor is in water, the led is on and it works with 12 v dc. I will use 12 sensors in the design of the card, and when the sensor does not see water, the led I used on the card will turn on and the relay and buzzer will work even if any of them are lit. I don’t have much experience for design. Can you help me with this?

this requires you to design a schematic that describes your idea. We have so many commercially available water level detectors and I could advise you buy one of them and have a look at its features, manuals, and operation then try implementing one. Thanks
