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!

    it should be an analog pin switched it to A2 and it works fine now

    Is it possible to use any kind of microcontroller here? Like arduino uno or nano.

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