Hello, would it only work with 4 levels???? using only 4 CI ports to monitor 4 level indication LEDs or would all CI ports be necessary??

[@bajlurrahaman6111]

Hi I am trying to make this but as soon as connect wire with IC’s input pin led little glowing water touch or not. what is the issue? How to remove this sensitive power ?

[@ahsanshawon2347]

is it based on conductivity of water??

[@mithila93]

I have made this. Workings perfectly. After few days it’s not working.
What's the problem?

[@TalasSikopat]

You can't dip into water permanently, it will initiate electrolysis process, wire will get corrosive

[@pit3835]

can i use 12 volt adaptor cause 9 volt battery is not sustainable? I want to use it as permanent in my 2000 L water tank

[@hemantkumar.23]

You make and use in 2000 l

[@devanthiranvijay]

Is this works only on salt water i tried this but works on salt water only

[@anuragprojects]

Yes

[@imamuddinkhamundali]

Iske liye kitne volt DC power supply chahiye

[@anuragprojects]

5v

[@NareshKumar-qc5yt]

How to get this

[@timmappanaik729]

could you get me a water level indicator ? what is the cost ?

[@sridharkrishnappanavanerth3388]

Sir, Dont use any kind of background music, use your own voice to explain the circuit functioning along with circuit diagram..👎👎👎

[@hemantkumar.23]

Isko real mai 3000 liter wala tank work hoga

[@MDR5213]

👍👍👍👍👍⁦😊😊😊

[@gyanusoft14]

I have made this using bc 547 transistor....

[@amitechsharma]

NEW IDEA PLEASE MAKE, TANK ME TO 4 LEVEL KI WIRE JAYE PAR MAIN UNIT SE 2 SIGNAL WIRE JAYE.

[@johncrunk8038]

So many problems with this. Soldering with no mechanical connection. Why not at least use a perfboard? A DC sensor is just looking for electrolysis and corrosion.
