Electronic – Water overflow pail detector

waterproof

I am looking for a "water overflow pail detector".
It basically will make some sound (e.g. beeping) when the water in a pail was about to overflow.
The detector must also be water-proof otherwise the electrical source to this detector will be short-circuit.

I have a very slow running tap that I used to fill up pail to wash my car.
However, I don't want to sit down there watching that slow tap to fill up the pail and
I also don't want it to overflow if I just went to watch the TV.
Therefore, I need to put that detector on the pail somehow in order to detect if it is about to overflow

I am not looking for a detector to measure the level of the water in the pail or tank or something like in the link – Level of a water tank with a microcontroller

  • Google: water level detector circuit

  • Click on "images"

MANY water level detector circuits each with its own web page.

This should suit your need.

A slightly different way:

N1 can also be 74C14, 74HC14 or any "Schmitt trigger" CMOS gates.

Float switches:

Have a look at these images "float switch" .
Each one of these images is hot linked to webpage.

These are probably even more likely to be apposite "float switch" bucket

From the above link:

Using "float switch" low voltage

This looks about what you want. Discussion here

All these come, as you will have seen if you looked, by using a simple Google search with some obvious terms and then looking at "images". A very powerful tool. Well worth spending the time required to learn how to use it.
