How to make Water Pump Automatic Switch ON-OFF Circuit | Water Level Controller with 555

In this project, I have shown how to make water pump automatic switch ON-OFF circuit to control the water level automatically. I have used the 555 timer IC for this DIY water pump auto cut switch circuit.

With this simple 555 timer circuit, we can stop the water overflow from the water tank. And the pump will automatically start if the water level becomes low. So we don't need to start and stop the pump manually.

I have published a new water pump controller circuit with more features. Please click the following link to watch the tutorial.

Download the PCB Layout for Automatic ON\OFF water pump switch from the following article

Required components for the water pump automatic control circuit
1. 555Timer IC (1no)
2. BC547 NPN Transistor (1no)
3. 1k 0.25watt Resistors (R5, R7) (2no)
4. 22k 0.25watt Resistors (R1, R2) (2no)
5. 180k 0.25watt Resistor (R6) (1no)
6. 1M 0.25watt Resistors (R3, R4) (2no)
7. 100nF (104) Capacitor (C4) (1no)
8. 1N4007 Diode (D6) (1no)
9. LED 1.5V (1no)
10. 12V SPDT Relay (1no)
11. Connectors & IC base (4pin)
12. Zero PCB

Here, I have used a 5V pump to show the operation, but you can also use any single-phase pump. Please select the relay as per the voltage and current rating of the pump.

After watching the video, you can easily design this automatic water tank level controller motor driver circuit for your home.

If you face any issue please let me know in the comment section.

Pls do not connect 220v AC current if u are using 5v pump. I tried this and my 2 pumps are blasted. So i connect 9v battery supply instead of 220v and guess what! It works 👍.

You have a great quality of helping others, keep it up. Thank you man.

I learned the difference between TRIG and THR, thanks :)

The common, pump ON and Pump off wires will get oxidation after some time due to electrolysis process.

[homoudalyahya]

Great video, very clear demonstration, and above all sharing the PCB diagram. Thank you so much.

Please let me know that the power supply wire is directly be plugged in the swich board or you use the battery

Thank you for such a nice home remedy "do it your self tech project" .Your presentation is very good.

I want to add one observation to this effort. Generally you will find that water is pumped from ground floor water tank to the overhead water tank. The gadget you have explained will serve good purpose for overhead water tank. However a person need s to ensure that there is sufficient water level in the ground water tank. If that is not ensured the pump may have a dry run for a long time till the ground water tank gets filled with the water. This is a dangerous situation since motor may burn. Plz consider to add another water level sensor for the ground floor water tank. The pump should operate only if there is sufficient water level in the ground tank.
Secondly if the electricity suddenly goes when the pump is running the pump switch must become off automatically inspite of the water level sensors giving signal to start the pump switch. Else when the electricity resumes pump may suddenly become ON again.

Thirdly there should be an isolation switch for this automatic level controller unit, This will be needed when there is leakage of water in the water circuit and needing a repair . This will be leading to hunting of the pump On/OFF condition till repair is done and may not get noticed easily.

If you swap the depth of the Red and Green wire in the Tank, you can change the pump to be a bulge pump for boats but put the pump in the tank. Once the water fills the boat and water reaches the green wire which is your safe maximum level of water, then you will trigger the circuit which will keep pumping till the water falls below the red wire and will turn the circuit off. As water fills in again, and reaches tge red, nothing will happen. But when the water reaches the Green wire, you will trigger the circuit and tge pump will run pumping the water out till it drops below the Red and Green wires.
Give it a go.

Brub i got 6th place for this participating in state electronics work experience fair 🎉😊

May I suggest, you could put a drain pipe with a height of 35cm above the bottom of the tub. Then you may attach to the drain pipe a N/O mini gas solenoid valve to it & then on of its lead wires is the same attachment to your water pump. So if the water pump is turned on, simultaneously the solenoid valve shuts off not letting water out & as the water pump turned off the solenoid valve opens & releases water onto the reservoir bellow & the cycle repeats as the controller dectects that the water in the tank is low.

I hope it works.👊😁

As you are using DC current in the probe immersed in the water, it will start electrolysis and corrode the probe material ( even S. S.) and the wire connected to it. Use ac voltage for the probe. Needs a better ckt. Good work. Instead of using + ve for common probe, better use ground.

I like ur plastic and papers pcb idea👍👍👍

[shvideo]

How so creative and neat. Great job my friend! Thank you for sharing.

[shekarv]

Hi dear, I like it today. I ll assemble tomorrow.

[dwiindri]

Terimakasih telah membuat rangkaian on of water pimp saya akan mencoba membuat untuk tandon air 👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍👍

[veeem]

Very nice design circuit, tried it and it works fine like in your video
The only problem is the common probe (sensor) starts getting corroded over night, if the sensors in some way is AC volts this electrolysis won’t happen, please design
Thanks for the video

Thanks boss. Muze nahi lagta isase behatar koi technic hoga banane ka. Kam like dekhkar dukh hota hai. Koi bat nahi.👍

[قناةإخترع-شن]

Peace be upon you and God’s mercy and blessings. Thank you for your wonderful ideas. I tried this circuit, but there is a problem. The green lamp and the relay work, but when I touch one of the capacitor wires, it does not work when I press the button, nor does it work when I press the mount control. There is a problem, which is the reason for asking the question: Why does the infrared receiver component heat up?

I'm a hobbyist, and this video attracts me. Now I want to make this project. Where I can get all the components (without the 230v pump) in on one package, can you help?
