IoT Water Flow Meter using NodeMCU ESP8266 & Water Flow Sensor | Measure Water Flow Rate & Volume

....................................................................................................................................................................................................................................

In this project, we will learn how to make IoT Based Water Flow Meter using ESP8266 & Water Flow Sensor. We will interface YFS201 Hall Effect Water Flow Sensor with NodeMCU ESP8266 Board. We will display the water flow rate & Total Volume in 0.96″ OLED Display. We will then integrate the hardware with IoT Server. For IoT Server, we will use Thingspeak App. The water flow rate & volume data can be uploaded to Thingspeak Server & can be viewed/monitored from any part of the world.

Water Management System is an important part of City Management. Water management involves supplying water according to the real requirement & without wasting Water. Therefore it is very important to measure water flow rate and volume. Without measuring these parameters, Water Management is almost impossible. Also monitoring the Water Volume, Flow Rate & Water Quality remotely using Internet Connectivity has become very essential. Therefore there is a need for Monitoring Water Management System Online.

There are so many Water Flow Sensors available in the market but are too expensive to use and afford. As a result, a low-cost water flow meter is required. So we will use YFS201 Hall Effect Water Flow Sensor with ESP8266 & design simple IoT Based Water Flow Meter.

Amazing, Thanks for such an informative video. Can you tell me if I can connect 4 flow sensors to a single NodeMCU and get the 4 different values at the same time? also how can the water volume data can be stored for future trend analysis.

[EvertvanIngen]

I was hoping to see the custom PCB from Nextpcb... ohh well

[VenkataSuryaSundarVadali]

Good project, but one thing I've noticed is that you wasted the water you measured. Please stop wasting water as water is precious and scarce. So please utilize it carefully. Thank you and wish you a great day ahead and a healthy day ahead. 🐈😿😸

Bro, I feel that if we place the sensor in vertical position we may get more accurate readings....
What's your thought on this?

[fidal]

Good evening, on your thingspeak page, you've got a flow rate and volume graph. How do I get the volume graph to show total liters passed through the sensor?

[adilrehman]

Thanks Sir, I was in a trouble for a long time. This video lead me to solution.
👍👍👍

How does it work when the GPIO input of the esp only has 3.3V max. It will. Damages esp quickly

[conradocamilon]

thank you very much but im planning to use esp32 sim800 because we dont have wifi in the area. Can you help me

[fede_lopez]

Hello, i done and works perfectly! one question, have you any way to sent via mqtt ONLY the differences to avoid send the same data continuously?
Thank you.

[mdshayed]

Thanks for any video.... i like your all video...
how many volt water pamp ?

[josephus]

please tell me why this error is occurring during compile: error: expected initializer before 'pulseCounter'

void IRAM_ATTR pulseCounter() others mentioned getting this error but it has not been addressed in the tutorial link. thank you
addendum: for anyone else with this issue, fixed by updating esp8266 to version 3.0.2 in IDE board manager

[kampermisajankovic]

I did everything according to the instructions. I'm getting an error:
compilation terminated.
exit status 1
Error compiling for board NodeMCU 1.0 (ESP-12E Module).
Does anyone know how to solve the problem?

[ninaduranisaias]

Hello friend, I have a question, the EPS8266 module does not connect to thingsbeak. How can I solve it? please help me

[divyashree]

What is the lcd which displays the rate and velecity

[gxseah]

I follow the exact same step, the water flow rate doesn't upload to the thingspeak,
I also tried to add: WiFi.begin(ssid, pass);
It still the same

[KhairulIkhwan-fqoq]

Want to know what software do u use to make that circuit plan

[mohammadmusa]

good morning sir please can this your system be applied in a borehole settings

[dilipsinghbhati]

if we use I2C 16×2 lcd display then what will be the change in code

[rahulr]

While uploading this error showing expected initializer before 'pulseCounter'
.please resolve ASAP

hello . you have how to reset meter by every day of time 23.59 ?
