Protect Your Home: Make a Sound Water Level Alarm

Good day to all!
Name of the homemade product:
Sound liquid level alarm (Liquid level sensor)
In this video review I want to show how you can make an audible water level alarm yourself from available things. This homemade product consists of only one transistor! Each of you can repeat this homemade product easily and simply! A useful homemade product that anyone can repeat!
This homemade product can protect your home, namely, it will not allow you to forget to close the tap when filling a bathtub, sink or bucket with water, and so on, the audible alarm will go off!
In my case, I took the radio components from an old unnecessary toy. The homemade product took five minutes.
I used the following elements:
1) Transistor:
N-P-N structure model: BC547 analog of this transistor KT3102G or KT3102E; you can also use BC550, BC337, BC639 or 2N2222, 2N3904, 2N4401;
2) As a sound signal I used:
a regular (3-5V) Buzzer, i.e. a buzzer (squeaker);
3) As a probe I used:
a regular eight-core network cable;
4) As a power supply:
I used a regular 9-volt battery;
Good luck and success to everyone, friends!
