Water Level Indicator / water level indicator with alarm / with ULN2003 IC 

zbrdst simple setup ... bohat behtreen

👍👍👍👍👍

Nice And Knowledgeable Video............

Best connection batai hai bhai ❤️

Good,friend! Tks...

Thank you sir

nice vedio

You gained one more subscriber you make things so simple. Do you think it will last for a longer duration?!

Nice circuit & setup, how can we use to monitor two water tank in a single power input

I want to use 5v mobile charger instead of 12 v power supply..

Pl make this circuit for 5volt dc

Bahut dino baad aaye sir. Very good video

We require both overflow and low level alarm system . You may please about the circuit diagram with two indicator high and low with alarm in both . So that we can switch off the motor before the overflow and switch on the motor before the drying up the tank. Manual control of motor. regsrds

Sir ji 470 ohm ka resistor kitne watt ka use kare?

Can I use 6v buzzer there?

Can we switch buzzer and led together

How do I snooze buzzer without pulling sensor wires? Please Reply.

9vlt battery kitna time tak chal sakta hai? Agar 24×7 days use karte hai to. Isme agar mobile charger use kare to konsa component change karna paraga?. Is accepted mobile charger? Waiting for your answers..... Thank you

3.7volt se banjaiga water lebal tenk

thanks bro! for nice video. can we use mobile charger instead of 9v battery?

Kay aap Bata Saket ho ki buzzer ko kuch samay bad automatically band karna ho to Kay Kare? Kyo ki tank bharne ke bad buzzer continuesly bajta rahega. Mai aapke jawab ka intazar Karuna

Sir kam components use kar ke 12dc ko 220v ac ka converter bnao

jitni ap nay wire use ki hai is mn boht acha work kr hai but wire length increase kro to koi led nai glow hoti matalb voltage ho jaty hain ko proper solution please.,?

Supply kaha se kiya

What is the best for water level circuit uln2003 ic or resistance

9.12 volt kaise Kaonsa mobile charger hai Please batyen

TDA7294+4558ic video

Sir...only red led will work on this circuit?? Can i use other colors? Pls help sir

Sir aap ka fone nambr mil sakta hai

It is not at all practicable because if positive terminal is let in to bottom of water tank, the sensor or wire is subjected to oxidation easily.If you don't agree, please observe the positive terminal immersed in water keenly,you can see chemical reaction.So whenever you release such videos that too connected with water / consumables , think hundred times about other ill-effects.

Sir my all led not glowing only red other goes dim wht can be reason or solution or i nees to use 100ohm resistance on every led ? I m using 12v 1a adapter

Uln2003 mei 9 _12 volt ki jagah 4.2 volt ki battery use kar sakte hai kya
