Is this project for a short term test or long term operation.

Option:

  • simple conduction
  • floating magnet
  • ultrasonic measurement
  • capacitance sensor
  • micro switch float mechanism
  • optical float sensor

Use either:

if (digitalRead(sensor_pin) == HIGH) do_something();`

or

if (digitalRead(sensor_pin) == LOW) do_something();

After hijacking one topic you now have started another on the same subject. Please read the forum rules, which have now been pointed out to you twice, before posting again. If you continue to ignore the rules you will get a break from the forum.

Thank you.

How drôle! :grin:

The point is, to pose a question here, you start by explaining yourself; your actual project.

Do you actually have a water sensor? What one is it? The Web link for it if you please?

What is the "tank" in question? Why do you need to monitor it?

What "Arduino" or similar are you using?

Once you start to provide information, we can actually help you. :face_with_raised_eyebrow:

I created a water tank monitoring system a couple years ago based on this

using a ESP8266 NodeMcu
i added flow meters to the in and out

water in the tank is old geometry
volume of a cylinder, radar tells you where the top of the water in the cylinder is.
then constants, water volume per gallon
