Good job man.
You just make it very simple
Thanx a lot!!works perfect...helped me a lot for my physics board project...:)
Very clear explanation,thank you for the video.
Nice job! Thats an awesome project.
up to how many LEDs can we add in this circuit. Can i use more LEds for more levels. If i cant what are the changes i shuld make in the circuit so that it works with more levels
hello! very nice your circuit it works fine, but...My son has an old VW truck with a water level sensor, and the dash board doesn't correspond at this model, normally there is a light wich comes on when there is no water, so the oposite job of your set up. Do you have any idea how I can have the light coming on when the level goes down? Also, I'm planning to collect the rain water and when there is not enough in the tank I could switch a pump to maintain a minimun level with normal water. Did I explain? When the level goes down the led should light up. Thanks for your videos.
Hi, I have done this in a big water tank (3500l) at home. Intead of BC548, I used ULN2803 transistor driver, which is probably not as sensitive as BC548. It worked great for a month, but than lights did not work any more. Only one worked. I checked the PCB board and there it all works fine. So the problem must be in water. Is it possible that the copper contacts in water oxidated or something like that, and the resistance increased too much?
THANK you
The circuit worked fine for me
Simple and practice for develop by my self ... thank you !
thank you so much at last my project is completed because of you
Very nice and simple, through wise thinking, setup.
well done. nice video also of the steps.
the project was actually nice!!!!!!!!!!!!!
Thanks Man. Your Project Is The Best And Simple To Assemble. Can You Provide The Block Diagram Of Your Circuit. I Would Be Grateful.
Dude very nice you made it easy and effective (Y)
It works for me.. Thanks
.. Iam grateful 😁👍❤️
That's very awesome. One day i will try to make it
from where u have taken or bought buzzer
I am using a mixed resistor which is all in like 330 ohm, 1k, 220 ohm all in one so is it fine!!!!
keep up the good work
Thank you for tutor! My first memory, I will be fixed it.
What I mean is , if I were to increase the number of levels indicated and therefore also the number of led in the circuit, would the resistor used be the same or different? And if different, how would u find out the resistor used for the new circuit?
hi is this a series or a parallel circuit?
Please clarify about 330 Ohm Resister. When asked about this they are asking more details about the 330 Ohm. Please Clarify the full specifications of the resister. Regards.
hey dude can I use 220 ohms resistor instead of 330 ohm resistor
Thank you
nice job!
hey can i use 220 ohms for this ?
Hey I tried d same as in video!!..but d buzzer sounds continuously irrespective of d water level ...what is d problem??n ly one led lits up?? Plz help??
Nice DUDE!!!
hellow.. cant we use 12v supply..?
Along with ohm you should tell the color of the trasistor
thank you buddy... it works (y)
why should we use only these apparatus?......could u explain us the working of it?
Very interesting, thanks
how are the wires to the beaker are connected??
You are the best ;-)
Thank you ,it easy to do
were they copper wires?
brilliant....super
I did it .. Thank you very much
Why we use 330 ohm resistor is it compulsory
THANX, It's working
how can we solve the same problem using computing ? I mean when water tank is about to get full you get a notification right on your phone
Hi your video shows awesome work and I am trying to make it
because tank is on the 4th floor and everytime one has to go up to see
if it is filled.
I have made the circuit as described. Previously I used lower resistor
so the led got burnt but putting wires in the water it was lighting (aft
sm time led burnt). Then I used 1k ohm, it was still lighting but very
low. Later I learnt the colour coding. Now that I have learnt the colour
coding of the resistor I have a 220 ohm which I am using with 547
transistor. Its not working. I have tried with 100 ohm. tried series
with 220+220 ohm. No luck. Now am again using 1ohm & 1k ohm (which
were working previously) but even they are not working now. circuit is
as previous. every wire connected to breadboard and respective place.
Can u tell me what is the problem? Is there any way to check at which
stage current is coming or something.
You must use electrolyzed water or salt water you can t do this project with normal water..i think
@@veskosberezz7807 tap water is good?
thank you so much
can I use 220 ohm resistor?
Thanks, its working..
what is the working temperature?
I have a doubt ..... won't this setup work even without the transistors ????? Or is it because enough current doesn't pass through the water in the bowl ????
try to work on you camera,lighting,editing skills then you could gain more viewers anyways keep up the good work
Gaurav please reply..
i was asking that do we need to use water or electrolysed water?...becuz the lights are not glowing using normal water
i have done exactle the same way you have
PLEASE REPLY BRO
ya, bro this circuit does not work on normal water it's only working on the salty water or electrolyte water.
yes i know and i had to do it in that way in my science exhibition ...and i got 4th prize there.for this model
Same here...
really best work
very useful video.
Can you Give me please the copy of this complete report....
u r just awsm!!!!!!!!!!!!!!
Could you post the circuit diagram please
I don't understood the name of transistor could u tell to me once plsss
it helped me a lot tqqqq
helped a lot
led's are glowing immediately after connecting the battery without testing with levels of water what I have to do please reply
Rombha perumaya iruku di
i want transmit 8 points on 2 transmission line, how can i do that ?
I want to know that materials I have in which there is not a buzzer what I do.
i did the exp but light remains deam...what can be the issue
Can we connect B-10 buzzer in this??? How ??
in case that i want to make for my house water tank is the 9v battery is safincient for it (or) i should i connect a 220v supply for in that case how to reduce a 220v to 9v suppply for the circuit
have you resolved it bro?....i too have same problem?
u could just use a adapter which converts 220v AC to 9v DC instead of the 9v battery so that it it saves you from using a battery and replacing it every time. don't forget to buy its female connector along with the adapter..
Go and buy 9 v battery bro
It can't
is it possible to submerge the whole circuit without the buzzer underwater or would that be pushing it?
Toby Mohs I think that would be a little too far
good project
im increased the levels upto 4 & with 4 leds and 1 extra led for water flow with buzzer with 9v battery .. but it not work ... can u help me ...
What is the cost of buzzer
auto motor system bana ya hai with indication k saat but bhai tank bara hai jiski waja se last relay oprat nhi ho rahi hai , pani ki resisstence bohot hone ki waja se.
Nice
why cant we use different transistors?
will this work on gasoline?
sir could u send me the full working of the circuit Thank you
which type of transistor you have used pnp or npn??? pls reply fast
both Bc547 and BC 548 amplifier transistors are NPN transistors.
congratulations.
keep it up
why can't I was use a simple 9v circuit without transistor, with water as conductor
Can I use the BC548B transistor or it has to be this one?
jart122 any transistor will work
my led's all burned out i used 316 ohm resistors help?
good electronic
Sir the same resistors will be used ....... No matter the no of LEDs is increased or not....:)
very useful information
please give the ckt diagram also
thanks dudes😄
good Job Guys
brother can i use another transistor.?
like c 548.
resistor 1 k
?????????
Ananta Jalil BC548 would work fine
Gaurav Yash Jain - AYJ you are very smart
Ananta Jalil even 2N3904 Transistor would work fine(note: I made one already using 2N3904 Transistor)
need the project report of this project
facebook link is not working ..
no it is not working i tested it 3 to 7 times i have to submit it in 2 days wat i should do plz plz plz plz plz help me k
Is this a series or parallel circuit ?
+mohammed qassem i believe this would be a parallel circuit. Because the first LED doesnt trigger the other LEDs.
Can u tell me why u used a 330ohm resistor?
It is used to limit the current flow in LED else the LED melts drawing more current
why isn't mine working? I did every exact thing. Once I connect the battery to the breadboard, the buzzer goes off. Why is that?
please answer as soon as possible
does it really works?? :o :O
thank you so much for this
Does the water contain salt? How come the LED lights up when water touches wires in the bowl?
stompdirtyyard distilled water has no metal ions in it so it can't conduct electricity (which is what i think you're thinking of) however, tap water has been through a lot of metal piping so it's picked up metal ions allowing it to conduct electricity
Harry O'Brien I was able to conduct this experiment and it worked but i used different schematic and an Arduino. To make the water conduct electricity a wire from the battery or the +5V of the microprocessor was directly placed into the water which would make sense why connecting the "level" wires to the gates of the bjt would make the LED's turn on when water touches the wires.
good project but there is particular principle involved
Tranresbreledbuzzwir is resistor transistor breadboard buzzer wire
helo. i have a problem with the buzzer. when i make a direct contact with jumper wire, the red led and buzzer functioning. but when i put into the water, only the red led functioning, buzzer does not produce any sound. please help me
tq
change the postive terminal of buzzer from the base leg to the emitter leg of corresponding transistr
Same prblm....
thankx, nw its working.....
