Excelente.
Poderia fazer um vídeo com o diagrama.

Ow cool vids 😎
Pl.make wireless/wifi/blue tooth water level alarm.It will be great service to our society....thanks...taking wiring to ground floor externally is painful,mainly because monkey,s they damage the cables.
I can make it but it will require batteries on both sides and changing the batteries regularly will be very inconvenient.
Kya ise 12 volt se chla skte hai
If your buzzer can run on 12 volts then you can make it using a 12v power source
It's best to use it with 5V source
Can we use BC547 B transistor
I have not tried these type of circuits with BC547B transistor but I searched it on the internet and am pretty sure that it will work just make sure to connect the Collector, Base and Emitter in the right way.
@@Srijan22 ok
I help you
first learn to solder component.
It is from 2.5 years ago. At that time I was still new to soldering. Anyways, thanks for your feedback.
Transister is not required .
The buzzer will not beep without a transistor.
Buzzer will beep without transistor.It is my experience. Take two battery connect in series. Both end of battery put in tank with long wire.
