The circuit is working 100%. Mine is successful now, is working perfectly..thanks.
Can u please give me your contact number?
Bhai ye circuit sach me work karegaa naa
Thank you so much for this video. I have used this circuit to operate a 24 volt sprinkler valve to maintain the water level in my swimming pool, and it works perfectly.
I guess you can be a great teacher, by teaching step by step, every details, wonderful video, even for those who have no clue about electronics. (like me), but the question is, if we want to reverse the function, instead of shut off the pomp, it starts the pomp and discharge the water, if not, what about upside downing the ruler as a sensor marker, does it make it to work revers? Thank you again and success in what ever you are doing.
Thanks for your comment,,.. and please see description for details..
Nice project. It good to show how versatile the good old 555 can be!!!

can you test what happens if the water level is below the red wire screw??????. if reply thanks
@@muhammadsaadullahsharif9637 even then water level is Below red wire... Motor is ON
if you sink only 12v wire & the top wire to water.. relay trips continuously
@@kabirprince8597 thanks for the reply. i am looking for a water pump protection controller. if there is no water in the main tank , the water pump stop automatically , the use of the pump is to fill the over head tank from the main tank. the circuit in this video can be install in the over head tank , very good video ,now looking for pump protection. .
waiting for reply thanks
Tried this build with an led bulb as output and it worked like a charm..Tomorrow I will try this build for my 1 HP water pump. Hope it works.
Hi bro it is 100% working for me thanks to u for this circut
Thank you man. Its working for my over head tank. and I used 40A SSR instead of 12v Relay.
I have seen many video related to it
But ur video is the most perfect one dat I found till dat
Well done
Keep it up 👍
Very good presentation
Perfect
Keep it up
Thanks
It very knowledgeable video I like thanked
Thank you very much, My fish will be happy now
Sukriya dear sir your project is the best.
Hi very good circuit if you can still modify it by give auto & manual switch control with adding sump water level also please.
You tried to convince the subject very well.... Your video making quality is also too good.
Wow this can make me automatically subscribe.
I have tested this with Every circuit app but its not working. I have seen the same circuit in all of the other RUclips videos but no use . Can u please troubleshoot this
1. Is there anything we want to do while we turn on the circuit

Which relay i have to use for submersible motor?
Project successful I grateful for you
Successfully huwa Bhai aapka
thank you for the project. very nice. could clear a doubt i had? what does the red wire does? which level it controls? thanks.
i also have the same question, if the water level is below red what will happen
thanks a lot bro. mine is working with 2 hp submersible pump.
lights get on. and when i first power this circuit relay sound once. and when i tried to test it with water levels its not getting off. means not switching or getting signals from water. no trigger. kindly tell me whats wrong? But i used all resistors 10 K 1M OF 1/2 WATT ? Is it any problem using 1/2 watt instead of 1/4 watt? PLZ HELP ME
Hello, since 12v and 1A adapter is been used to power the circuit. Is it still needed to add circuit protection like short circuit and overload protection on the device?
Excellent the Best
Brother dry run protection is needed in this circuit . In case if motor unable to pump it should stop automatically otherwise motor will burn.
Thanks i would like to try your job brotha
Will there be any problem if I run it with 12 volts 5 amps? Is there a possibility of IC nust? Plz ripley me
At last I have done it. Thanks once again for your support. Now it works perfectly but ic still becomes hot when I run the circuit. Plz suggest..
check supply voltage.
When I used 12v 1amp DC adapter for powering the relay starts on and off in a strange speed why? But when I connects 12v battery (9v+3v) it works fine. Can you tell me the problem? How much amp perfect for this circuit?
the adapter you are using is sufficient for this circuit. but always use a good quality power supply unit. A poorly-designed switching type PSU is not a good choice for any circuit
Is it only for the project? Or can be used for home overhead tank as well With the same circuit and components.

Thank you for this video. I have watched dozens in my search for a sump pump control circuit and this is by far the best, especially where you show the soldering process. I have two questions and three suggestions and would value a response.
Q1 : I want to use this to control a sump pump i.e. Switch on at high level, off when low. Can I just swap the high (6) and low (2) level sensors on the IC555 to high (2) and low (6) ?
Q2 : I want to use this in a rainwater collection system so will it work given the low conductivity of rainwater? If not, is there any way of overcoming this without resorting to electromechanical devices such as float switches?
I admire your patience with answering the same questions over and over again. You are a Saint...
S1 : For those asking for circuit diagrams, suggest that they simply set playback speed to slow, pause the video when it shows the the diagrams and do a screen capture.
S2 : Suggest in the description as well as your opening comment that viewers first read through all the existing comments before asking questions since it is highly probable that they will find that their question has already been asked and answered.
S3 : Place some links to videos about how transistors / mosfets / diodes / etc work. Resist the temptation to to spoonfeed.
Thank you again for sharing. I has rekindled a childhood interest in electronics that was put aside when funding for studying electronic engineering was not available but was for civil engineering. I am now retired and enjoying dabbling again. Learning new things is great for keeping those brain cells active and fit.
Thanks for your comment''
So you want to use it on a sump pump, but by swapping high(6) with low(2) level sensor will not make the circuit to work the way you want....
here's what we can do:-
Option1- Connect AC wire to the N/C terminal in place of N/O terminal of relay i.e. In the circuit use 'N/C terminal of the relay' instead of 'N/O terminal of the relay'....and the circuit will work the way you want [No need to change any other things in the circuit].
Option2- In the above configuration Relay will be in ON state when your motor is OFF and vice versa. so most probably most of the time your relay will be in ON state, to overcome this we can do some modification in the circuit,,,, If you can give your email address I can send you the modified circuit diagram. .thanks
and yes, this circuit will also work with rainwater.
My tank is at 3rd floor around 20m above, so can i run sensor wires that long?
Also is it 100% safe to use in our water tank?
Hey, is it possible to use BC547B instead of BC547 in the sump pump circuit? Thanks
Sir nice video, i have question, how much distance is suitable for this WLC
sir, now it working i rebuild that thing again. thank you
Greetings, I am beginner in electro, schematic that you have shared with us, I managed to run it, but if it pleases, to be added again for when the well water has receded, the water pump engine will turn itself off at its sensor limit, even though the sensor to the water tank gives orders are still filling in, thank you.
I have made this circuit but the sensor wires are receiving almost 21 volt ac current while checking in multimeter...can u pls help me
is the water in the tank going to get current? How to make sure its safe for current in the water (not more than how many amp) ?
Sir will the water supply will stop if it will reach a specific point in the water and then again fill up and stop at the top Point . Please reply fast I want to take the project
Considering the circuit is in power off mode initially. If the water level is in between low and high sensors and power on the circuit, then 555 IC output is not predictable, so motor may turn on or off. Do you handle this condition?
when the main power supply disconnected and restored then;
) if the water is touching High-level sensor -- Water pump will be in OFF state.
) if the water is between High and Low-level sensor -- Water pump will be in OFF state.
) if the water is below Low-level sensor -- Water pump will turn ON.
what is the use of 12v wire that has been put into the water , will this circuit work if water is pure
What kind of motor used ?
Hello,
I need to use this circuit to empty a canister when water reaches a certain level. Reversing the order of the probes is enough?
Thanks!
@Razvan Suhanea
by reversing the order of the probes, the circuit will not work the way you want. I have updated description with some modified circuit diagrams, please see description for details.
I made a circuit exactly as per your instruction
High level cut off is working
But auto on function is not working after water reaching below the mid position
Please help me what to do

Sir can I use 9volt dry battery ??
Can 6v,7amp230ac relay use for 1hp induction motor??
You can use 9v battery for this circuit, but the specified relay may not be suitable for you.
can you replace the wire sensors with a capacitive proximity sensor?
Can i use another resistor on the place of 1m because i dont have it
Please tell me which resistor i use on its place plz tell me fast
any resistor between 500K to 1M [choose higher value resistor].
also, multiple resistors can be added in series to get a higher value resistor.
@@snnyhacksci.5984 but why higher resistor
Nice 👍
When I powered the circuit the pump starts and as soon as water touches the upper level wire the pump stops. But problem is that when water level goes slightly down from upper level sensor wire the pump starts again. But according to diagram the pump should be start only when water level goes below low level sensor wire. Can you solve my mistakes?
@Raju Kumar Pathak
The situation you are explaining will occur if the high-level sensor and low-level sensor are exchanged, see high-level sensor goes to pin 6 and the low-level sensor goes to pin 2 of IC.
also try after replacing R1 and R2 with 1K resistors.
check description for the circuit diagram
Thanks... I will try
Sir i have a smal submersible pump of 6v.. can i use that pump for this project? Will the circuit work or i have change the relay and resistances
Yes, you can use a 6v submersible pump, use 6v power supply for your pump(6v in place of 220v @ 0:50).
which motor pump is used in this video ? how many hp
Sir, i build the same as it and provide 12v 2amp input the ic is get hitted
Please reply I have only three day to submit the project...
Please check all your connections..
try after replacing IC with new one,
If your project is working and IC is getting hot, then problem might be with your power supply use a good quality power supply(Adaptor).

@@mohdwasim9610 Bhai capacitor nikal do ye kam karta hai..
any way of contacting you for one question of according to this tutorial?
When i put the wires in water the ic is get "hitted"
Sir can we use this circuit on 1HP or 2HP submersible pump..?
Hello bro help my problems is after water touch the high level sensor wire motor still on plz help me..... & plz replay.....
555 time is not working please reply bro how to check 555 ic please reply Malti meter
will it work with the same components for a single phase motor or else will it have to be changed if yes please tell
If your single phase motor is rated less than or equal to 1HP then nothing to be changed. For higher HP motor you just need to upgrade Relay.
use high amp relay for higher HP motor. Thanks
If i want use another voltage and amp relays, so please tell me how to select the REGISTERS, DIODE, AND MORE...
PLEASE REPLY....
the circuit will work in a voltage range of 5v to 16v, choose a relay according to the supply voltage i.e. use 6v relay if you are using a 6v power supply.
If the supply voltage is between 5v to 9v, you can change these values; all 10k to 1k, 1M to 560k and 2.2k to 560ohm. .thanks
Hi I really loved your video..
I need a small help..

Can i use 6v relay instead of 12v?
Hello. What if we use a 3-5V water pump is there will be changes in the circuit? Thank you so much.
Please see descripton
I used 12v Dc pump but it's not working. I need help.
shall we use 5v relay instead of 12 v and power supply?, because i want to use it for cooler only not on 1 or 2 hp motor
@Rohit Patel , yes we can use a 5v relay with 5v power supply.
and not necessary but you can change these value in the circuit- all 10k to 1k, 1M to 560k and 2.2k to 560ohm. .thanks
and 5v sugar cube relay will work fine for most of the cooler water pump.

Hello..I used 2n2222 transistor to run the circuit,its not working.its showing both green and red light at the same time when on.thinking may be is not connected to a pump that’s why is showing both at the same time.then I used 1hp pump,it’s still showing the same thing.which in actual sense,it will only show red light when the controller is on and the green light will later turn on when the motor pump is pumping,but is not.its not sensing the level of water to pump,talk more to trip off when full.whats wrong? And what could be the problem? Thanks.
have you connected 2n2222 correctly, as pinout(Emitter pin, Base pin, and Collector pin) of 2n2222 is different from BC547..
Ok.Don’t know if is well connected.but I connected my emitter to the one that passes through the 2.2k resistor,the diode and to the relay and my collector passes through the 1M resistor,timer,which reaches to the negative 12v.buh later interchange the connection of the transistor,but still not working. please tell me in details on what to do.

can we use 12v 350mA?
I do not really understand the working of the circuit... Can you explain the block diagram of the circuit board? Thank you.

what happens if the water level is below the red wire screw??????
Hi
SNNY Hack & Sci.
I consufused if i use 220V AC and Rely 12V, so is this working with motor 12v DC ????
thanks you .
you can use any motor, 220v AC motor or 12v DC motor, for 220vAC motor you will need 220vAC(as shown in diagram) and for a 12vDC motor you will need to connect it to12vDC supply.,,,, just pick a right relay, check maximum current that relay can handle and also check current rating of your motor, the maximum current rating of the relay should be higher than the current rating of your motor. .(specification of relay are usually written on it).
for example, If the maximum rated current of your motor is 5amp then you can use a 10amp relay.
small size motor usually draws less current and will work with most of the commonly available relay.
(This circuit requires a relay with a coil-voltage of 12V) ....

Dear
SNNY Hack & Sci.
I want to deep understand about circuit , not just rote learning,So could you tell me how to calculate to choose resgistor 10K, 1M, Capacitor
0,01uF and why you choose Diode
1N4007 and transitor BC547
Last time, i received your answer so well, i hope this time you answer my question thoroughly too
One more time , i must say thank you so much !
@Tiến Hưng Ngô
Thanks for your comment
.
.
It's hard to give a deep explanation of everything in a short comment.
I will try to explain a few of the above-mentioned point in short.
why BC547??
It is not necessary to use only BC547, we can use almost any NPN transistor, for example, we can use BD139,TIP122,2n2222 e.t.c
and many other NPN transistor. but why we have chosen BC547 and not BD139(for example). let's see some spec of these transistors.
the maximum collector current of BC547 is 100ma i.e. it can handle a load up to 100ma, small Sugercube10A relay used in this circuit draws less than 40ma of current, so BC547 is sufficient to drive this relay. now let's see BD139, it can handle a load up to 1.5amp(1500ma), yes we can use BD139 but it will unnecessarily increase cost and size of the circuit, it will be something like using a mini truck for transporting 1kg apple. .now let's see other condition, If you are going to use this circuit for high HP motor then this Sugercube10A relay will not work you will need a higher amp relay, here minimum current required for relay(relay coil) to work may be higher 100ma(you will need to see spec of relay) and if it is so, then you will need to replace BC547 with 2n2222 or BD139 or any other similar transistor.
why 1N4007? ..similar situation with this, there are many other options we can use. 1N4007 is used as a flyback diode in this circuit.
why 0.01uF?? actually, it is an internal matter of IC 555. when Pin5(control voltage Pin) of IC555 is not in use it is usually connected to ground through a small value capacitor. but why??.. circuit will work even without this capacitor but if it not connected, the circuit will become immune to noise, it can pick up noise and rf which can cause some error in the functionality of the circuit..it is something like, you get a cut on your finger and you are not using a bandage.
For a deep understanding of this circuit, you will need to understand these things,(just google them)
)Voltage divider )Resistor at transistor base )current limiting resistor )Internal structure of IC555
)Comparator )SR Flip Flop )NPN transistor )transistor as a switch )Flyback Diode )Ohms law.
