+chathuranga sampath Thank you very much

+Mayank Agrawal Happy to help you

+Syed Hussain Welcome

+Mansing Sawant Thank you

+B Kumar Ok, i will absolutely make this type of video later. Thank you again.

I have a waterfall, solar. I use this with a smaller pump to refill waterfall tank. You can put a timer on relay to shut off the filling pump after so many seconds.

Nei es se pani me current nhi ayega.

+Syed Hussain It does not matter what HP motor you are using. Because the relay is connected to the starter.

+techniques at home Yes, it will work fine.

You can use any, it depends on which voltage you are feeding

ashok mukka in the circuit diagram the upper red wire is 12v + wire and lower black wire is negetive input. See the diagram carefully ground sign is given in the emitter of the transistor. Thanks for watching

+Zahid Hussain you can use any NPN transistor whatever you have. Just connect the pins correctly, I mean ECB of the transistor.

+Syed Hussain As it is DC relay, so you have to manage a dc power source. Otherwise it will burn. You can use a 6V Relay and old cellphone charger to power it. Thank you.

+Shameem Rajpoot Any power source will work.

+Tinu Tom Yes 1n4007

+Kristofer Valencio Here IN4007 to absorb the voltage produced by back emf of the relay's coil when the transistor is being off BC547 to act like a "SWITCH" 100ohm resistor to limit the current going to the base of the transistor. Thank You.

thank you very much for your explanation

and can i use 1N4002 diode?

+Kristofer Valencio yes,you can use IN4002 .

I will make the diagram and send you today. Thank you

hello Sir, I haven't received any email from you for my inquiry. please send me the circuit. thankyou.

+Pravesh krishnan What will be the best option for you 1) Circuit with two relay and two transistor with same schematic. Or 2) circuit with one relay and three transistor and some resistors to fine tune for better result. Finding your next reply.

So base on your first option, first relay in tank 1 will be N/O & tank 2 will be N/C which is connected in series using the same schematic. Am I, right? second option I don't understand :( Could you please hand sketch a simple diagram and send me

imgur.com/ouwSplV Sir, please find the link to the diagram that I have made. please check and let me know if I need any corrections. My PCB board is in progress. Thank you for the kind help.

Yes friend

+Mayank Agrawal yes

+prashanth sr Yes it will work

+KBN World Details of relay Input rating. 12v dc Output rating. 250v 7a Or 120v 7a Details of diod 1n4007 Or any 1n4000 series 90v 1a. Thank you for your query.

+Anuj Kumar it depends on your relay voltage ,if using 12v relay then supply voltage also be 12v and if 6v then 6v.

Prabhu Kumar it depends on your relay's specification.

1A or even 500mA will work

thanks

You have to increase input voltage And decrease the base resistor But careful with relay's max voltage

Mayank Agrawal nei aap ise direct use kar nei sakte kiuki e utna load utha nei payaga, aap ka jo starter hai usse use kar sakte ho. Description me jo video link hai usko jara dekhlo.

ELECTROD PALL sir matlab starter pe ye relay lagana h jaise apka next video me h

ELECTROD PALL sir circuit yahi h na uss video m

Mayank Agrawal ha yehi circuit use kiya hai.

+Piyush kumar That is why the relay does not take the load of the motor, It just push the { off } switch, the circuit is made in this purpose. And thank you for watching.

1/4 watt

+Rajnish Prakash nei e jal nahi jayega,

ELECTROD PALL . Par aap to 12v relay use kar rahe ho

Rajnish Prakash motor directly to relay se joora nei hoga. Relay se jo two wire nikal raha hei wohi wire starter ke OFF switch ke series lagana hoga.

ELECTROD PALL . Thankyou

Contractor use karo or 12 volt ka

+David Sailo No, it is not dangerous. Just solder the AC wire to the relay safely.

Tech Ideas thanks... i will subscribe ur channel

+David Sailo Thank you very much

+Vanshdeep Manerao You can use any low power transistor whatever you have.

+pradeep j Here diode acts like a protector. It absorbs the reverse voltage produced by the relay coil when it switched off and magnetic field collapses.

+Naved Ali Eh circuit to wohi kaam karta hai

12v supply

No, you have to manually ON the pump switch to restart

+Deepak Rajbhar To water tank

+Tinu Tom Then just put your motor in place of relay. And the diode attached don't place the motor with out the diode, it can kill the transistor. Thank you

To protect the relay from voltage surge

+Electric guidance In my home it's working since 3 years without any problem. Thank you for watching the video.

Tech Ideas chalo bhai tajerba kr k dikh lite hn

+B Kumar 1.It called relay 2. It only push the ( OFF ) SWITCH. so motor current is not passing through it. 3. No you have to power it from another dc power source. 4. ignore it because the coil is inside the relay. 5. To activate the relay you have to get a dc power source depends on relay's specification and it can handle 220v 10 amps. 6.you just have to on the pump, when the water tank full the pump will automatically be OFF. 9. It will cost around 20 Rs (inr). Thank you for watching

+Pradeep Bhaskar This circuit automatically OFF the pump when water tank is full only. And it does not restart the pump, you have to ON the pump when needed. Thanks for watching this video.

Tech Ideas Lekin aapne jo video me bataya, uske mutabik to jaise hi wire paani ke baahar nikala bulb ON ho gaya. Switch off kaise hoga bulb ka main switch
