How to Make a High Quality Water Level Indicator | 5 Levels in a PCB

How to Make a High Quality Water Level Indicator | 5 Level in a PCB
A water level indicator is a system that relays information back to a control panel to indicate whether a body of water has a high or low water level. Some water level indicators use a combination of probe sensors or float switches to sense water levels. “The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or any other water container. The purpose of a water level indicator is to gauge and manage water levels in a water tank. And this is my DIY one.
Components Needed:
5 pcs BC547 NPN Transistor
5 pcs 100 ohm resistor
5 pcs LED lights 5mm
Insulated wires
Soldering
9v input

Amazing you have a great job.

[@JaviersDIY]

Thank keep watching

[@fixnreview]

Nice one! Watching from Ormoc City!

[@JaviersDIY]

Thank you sir. Keep watching

[@fixnreview]

@@JaviersDIY yes I will

[@tiosegayo7119]

Good job

[@JaviersDIY]

Thank you

[@copernicusyew3930]

Hi, this is a great video. May I know if I can power up the indicator using a DC 9V battery??

[@JaviersDIY]

Yes sir you can use 9V battery as Input

[@eyadsmadi7802]

Can I use a 9-volt battery as a power input?
Can it give results at long distances, like 15 meters?

[@JaviersDIY]

no sir

[@pit3835]

i will use that in our 1k Litwr water tank
,,but instead of battery i will use an 12v adaptor with 2 amps, do you think that this will be safe?

[@JaviersDIY]

No sir. But you can use a regulator in order to have a desired input voltage

[@pit3835]

Sir we can use buzzer instead of last led??

[@JaviersDIY]

yes sir you can

What is the name of green element which is mounted on pcb?

[@JaviersDIY]

Terminal block sir

[@jimmybusto935]

Nice sir you demonstrated but the value of the resistor wala.the transistor no. Ito ba'y pnp or npn and the supply voltage.please label the diagram.tnx

[@JaviersDIY]

Nasa description po para malinaw sir.

[@BinoyAnto]

Can I use a 18650 Battery (3.7v) with 2N2222 Resistor? Will this work in same manner and with same connections, please reply..

[@JaviersDIY]

No sir because it only works with the same value of transistor not resistor.

ARE THE COPPER STRIPS NECESSORY? CAN A USE A PIECE OF WIRE INSTEAD?

[@JaviersDIY]

it's up to you sir, you can use anything as long as it makes you comfortable and easy. Thank you

[@anjenayskumar2429]

In my circuit only the first 2 leds are lighting up.. what would be the reason?. I did exactly as in the video.. will it be bad transistors? Is it possible for the all 3 transitors to go bad? Please help 🙌🏼🙌🏼

[@JaviersDIY]

@@anjenayskumar2429 you have a bad transistor I think.

[@johnpaulrosales184]

Kaya ba ng 12v supply yan?

[@JaviersDIY]

Hindi po sir. Masusunog lang po yan

[@callmerel2809]

Please help, why do you need to use transistor if the water can connect the positive wire to the led ?

[@JaviersDIY]

Sir using transistor is more effective than depending on the water.

[@callmerel2809]

@@JaviersDIY why is that ? can u please explain

[@JaviersDIY]

Using a water as a conductor is not a proper way it has a low conductivity if you use DC supply but If you use a transistor like I use the video it is more effective and sensitive because it needs a ground only. That's I prefer to use transistor than water only.

[@callmerel2809]

@@JaviersDIY between the transistor and the water, do you need to put resistor in the base transistor to limit the current ?

[@JaviersDIY]

Yes sir.

[@beyond4682]

Sir , saan po konekted qng ground.

[@beyond4682]

Umiilaw yung LED ko kahit hindi pa naka kabit ang wires bakit kaya

[@JaviersDIY]

Sir. Baka po nakadiretso doon sa ground

[@JaviersDIY]

Try nyo po tingnan kung wala bang wrong connection mostly kasi yan yung mga dahilan.

Dear there are 1000 projects on water level indicator on youtube but the problem is all are same. It is 998th project out of 1000 projects. Please don't copy and do anything else that should 100 % your.
