How many times have you flooded the neighbors below? How often do you forget that you fill the bath and when you enter the bathroom, you find a pool of water on the floor? This happens to everyone, if not every time, then at least once a month or two. To avoid a ridiculous situation, you can ask someone to remind you, you can put a timer on your mobile phone, or you can use the sensor, which will notify that the bathtub is full. The manufacture of such a sensor is dedicated to this material.
So let's see how this makes the author so useful. homemade:

To create your own sensor informing about filling the bath, we need the following components:
- Siren;
- Two nails;
- Two pieces of foam;
- Two bars;
- A piece of copper wire;
- Two large nails per 10 mm;
- Battery;
- Battery mount
- Glue gun.
First of all, we need to drill two holes on the casts, as well as on the foams. The holes on one bar should not be through, and on the second, as well as on the foams, the holes should be through.
When the holes are made, we have to connect the wires coming from the alarm, as well as small nails on the foam. This should be done as follows. We connect the red wire from the alarm to one nail and glue this nail with a glue gun across the foam, that is, so that the nail is in the middle of two holes. Then we wind the copper wire onto the second nail, which, however, is not glued across, but along the length that is next to the holes.
The first stage of work is completed. Now we need to take care of the mount for our sensor. To do this, take two bars and two long nails 10 mm.
We push both nails through the through holes on one of the bars.
The second bar is not touching. Prior to this, we conduct foam with red wire on the nails so that the nail looks down.
Next, we conduct the second foam with a wire so that the nail looks up.
And now we take the second bar and close our structure.
The foam, on which a nail with a copper wire is glued, is glued to the bar.
Now you can take care of energy, that is, connect the battery. We attach the copper wire to the minus of the battery, and the black, which comes from the alarm and is not yet used, is a plus.
When a loose foam with a red wire approaches the bonded foam with copper wire so that the nails are in contact, the siren will sound. Thus, it remains only to put the sensor on the wall of the bathtub with the foam stick up. Water will gradually raise the free foam, the nails will touch each other and the siren will sound.
