Hello world! Today i made a simple flood alarm with a water level sensor. I do not sell these sensors on my website because they don't last very long when measuring water i will order gold coated ones and test them for a few weeks, but its very simple to build and useful for a flood alarm, beside that the sensor is very cheap. I'm sure this is useful for some. Follow the next step for the Schematic Code & Parts list.

Step 1: Schematic Code & Parts List.

Just wire it up like the schematic, upload the code and it should work.

Parts list.

  1. Arduino uno, I used the RobotDyn uno.
  2. Water level sensor.
  3. Buzzer.
  4. Led ( i used white)
  5. Jumper wire set MM/FF/FM

Good luck!

    You linked analog sensor and connected it to digital input. Is that correct?
