• IoT Based Water Level ...
For this NodeMCU ESP8266 water level indicator project, you can use any ultrasonic sensor as the water level sensor in the tank. You can always monitor the tank water level on OLED and if the NodeMCU is connected to WiFi, you can monitor the water level from anywhere in the world on Blynk IoT App.
In Manual mode, you can control the water pump manually from the switch and Blynk app.
The alarm will ring when the tank is full and when the water level drop below the threshold limit.
During this video, I made the circuit on zero PCB using the PCB layout, and also shared the wireless automatic water level controller circuit and source code.
If you want you can connect a relay to the control pump, otherwise you can use this IoT Project as the water level indicator.
During the ESP8266 project video, I covered the following topics:
00:39 Quick demo on water level monitoring system.
03:16 Required components for the ESP8266 IoT project.
03:35 Circuit diagram of the IoT-based water level controller.
04:14 How to make the water level indicator on Zero PCB.
05:13 Set up Blynk IoT Cloud for ESP8266.
07:44 Source code for the water level controller project.
09:48 Set up the Blynk IoT app for the water level indicator project.
11:40 How to connect relay buzzer with water level sensor circuit.
Required components for the automatic pump controller.
1) NodeMCU ESP8266
2) SR04M waterproof ultrasonic sensor OR HC-SR04 sensor
3) 0.96" OLED Display

Important points:
1. For the SR04M waterproof ultrasonic sensor minimum measure distance is 25cm, so the distance between the sensor and the full tank water level must be greater than 25cm.
2. As per the logic, the ultrasonic sensor will only calculate the water level if the measured distance between the predefined values for the empty tank and full tank.
3. Define all the distance values in cm.
4. You can press the button to stop the buzzer.
5. Here I have used an Active HIGH relay, so the relay will turn ON for the HIGH pulse.
6. You can either give AC supply, or 5V DC supply as shown in the video.
7. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.
This IoT-based ultrasonic water level sensor project will help you to maintain the water level in the overhead tank, also it is very useful to save energy and water resource.
If you face any issues please let me know in the comment section.

project is not good at all. i have done every thing right according to this video. problem 1: some time physical button work,most of the time it does not work but, blynk buttons are good.. problem 2: sensor giving lag result,some times water percent/distance is not changing as result pump is not working correct.

Hi from Argentina! What a great channel! Thank you so much for the info!
Welcome
Very nice project. I like how you made the paper templates for component placement and soldering.
Thanks
Superb job done. Appreciated 👍 your efforts
It's my pleasure
Firstly thank you so much Sir, sharing this valuable, informative & helpful Content with us. But I kindly request you this system makes for Terrace tank and underground tank both, if you possible 😇👍🏻
Thank you Once again 😊🤝🏻
Very good
Nice 👌
Mantap luar biasa ilmunya sangat bermanfaat, sukses selalu semoga ilmunya berkah. Salam..
Great video, please make another video of it using esprainmaker
Thank you sir 👍
Most welcome
Hi thank you for sharing, but what if i add flood mode, every movement of the water the alarm will make a sound? What code should i add?
Fantastic!
Thanks
We did a technology to get data from ultrasonic modules over same DC line so just can use 2 wires instead of 4 wires :)
I love your channel ❤
Thanks
Outstanding sir
Amazing
Sir please also provide zero pcb circuit diagram of home automation using esprainmker so that can we make pcb easily sir.
If the water does not rise for 10 minutes then the motor will go to sleep for an hour If you add this code it would be great.
Excellent
Thanks
please help my esp8266 is version 0.1 can we use the same libraries?
also i have done whole project but port is not showing in code
How can I remove the manual buttons and LEDs? I really like this project but seem like it can be streamed lined. Can this be done easily?
as per the schematic relay button2 was connected to D12 on NodeMCU,but could not find D12 on the board itself.
Wonderful shir
Thanks
Hello, can you please add a chart to the app so one can track the water level through time. Thanks
very good sir
Thanks and welcome
Is the demonstrated setup available as a kit to purchase from you?
Thank you very much for this project, I realized it but my card can't connect to the wifi while everything is well configured need your help please
Wonderful. Sir, u also made similar project using Esp32 and Blynk. Please make using esprainmaker
Okay
Bro can you make a project on automatic switch on for Generator when the current is cutoff
Hi, I am working on one of your project: Water level monitoring using ESP8266. I am facing a PROBLEM that my module is not connecting to Blynk. I have placed all the website keys to codes correctly but it didn't work
This project is absolutely good but you can add nrf24 module for wirelessly control and also add sump and overhad tank controlled by wirelessly
My suggestion is use low power module so it can be easily use in battery for sender side
Please upload this type of project becouse more practical and more usefull but need lots of skills thanks
Hi. Your project is great and very easygoing. I have tried it but I am facing an issue that during auto mode reading from the ultrasonic sensor is spiked above 100% frequently due to this running pump stops within short time. Can you implement any code by which if readings are above 100% or starting percentage for more than 2-3 seconds then only output count. Thanks you are doing a great job.
I had faced the same problem . There are wrong values in between which I was trying to filter out by using averaging and different formulas. I was not able to complete the project. Have you found any solutions yet?
Super super
Thanks
Can I add more water sensor and pumps? Maybe even a camera?
Great.. I try.. And.. Success.. Thanks... One again... Thanks 🙏🙏🙏
bro i have issue with the code , i already install all the library but still cannot compile it . can u share your code to help me ?

There is a MCB in the circuit. Please watch complete video
Sir, what will happens when the tank reaches 100% during manual mode. Will it gets off or we have to off it. Can you suggest or include protection of motor running during dry conditions that is to stop motor during dry conditions.
You can set the logic that if the motor is on by automated mode and if the current water level reading and the water level reading after 3/4 minute stays the same the motor to turn off automatically I think dry motor can last for somewhere around 10/15 minutes without any significant wear and tear
sir please help me. this code is wrong. complying error, what do you mean D5 meas V5?
Why does it come again and again?
Big drawback u can't extend the sensor cable . For real-time usage u need to keep all the things near to tank
I completely complete this projects but cant trigger relay of 5 v 30 A relay . I think relay needs to slightly increase voltage may b 7 to 9 v . Do u have any idea about this ? other wise my pcb board gone waste

Sir how to see internet is connected or not to nodemcu
Sir, please help me with the working of 5V 30 amps relay module like one you used in your float sensor video. I am facing problems with it. The relay is not triggering when connected to 5 V module . I also tried with another new 30 amps relay but it also does not trigger. Whereas 5v 10 amps relays are working perfectly with the 5v power supply.
Sir , please help me to fix this......
It is due to power supply. Use stable power supply.
@@TechStudyCell I am using Hi- Link 5 V 5 Watt power supply. The point is that if I directly connect the wires of the power supply to the coil of the Relay module so it works great but if I connect the wires in the connection points of the pcb ,the relay coil seems to be not energized properly. The 2nd new 5V 30 amps relay also acts the same. What to do?😔
Hello sir why code not done compile please help me
Bro can you add bom file of this project PCB
I HAVE SEEN MANY OF YOUR VIDEOS AND IN MOST OF THE VIDEO I HAVE SEEN THE PCB WAS MADE FROM A4 PRINTABLE LAYOUT FOR MAKING ZERO PCB.
BUT IN A VIDEO [[Project 🔥🔥 using ESP32 and Sensor with Fan Dimmer]]
YOU HAVE NOT PROVIDED THE PAPER PRINTABLE LAYOUT OF PCB TO MAKE ZERO PCB,
IS IT POSSIBLE TO MAKE A ZERO PCB FOR THIS PROJECT, I THINK YOU CAN BECAUSE YOU ARE A REALLY TALENTED GUY,
IF IT CAN BE DONE CAN YOU PLEASE SHARE THE PRINTABLE LAYOUT....
It's depends on the complexity of the circuit. Printable PCB layout for zero pcb is not possible for some circuit.
@@TechStudyCell Is there any way to attach a buzzer for the fan control and temperature display in this project....
How much cost this project
Bro make a automated birds water feeder
Ok I will try

Green led is Operating according to water level but relay is not operating
does need internet or just wifi?
For Blynk you need internet
Check it without wifi connectivity
It will work without wifi.
Please Sir make a water pump control project with esprainmaker
ok

@@ashaproductionslabs190hello, I'm also getting problem while compiling code but I installed all the library that he give on his website and then my code run without any problem.
In short solution is- Install library version according to his website and version given in code.
Hope this helps 🙂
i also have the issue bro , i already follow all the library but still have a problem , can u share you code for me try ?
The video and content are perfect, but the audio quality is inferior.
Bro your channel has potential, please buy a condenser microphone for voiceovers, it will sound much more professional, and trust me more people will watch it.
Thanks for the suggestion. Working on it.
Why doesn't the relay turn off?
Help plis
Find a salutations ?
I just need a water level monitor. How bro?
Don't connect the relay. It will only monitor water level
@@TechStudyCell Thank you for sharing.
Did this water controller work offline or not
Both offline and online. At offline you can monitor reading on oled
