In this IoT project, we are interfacing 40Kg load cell to the NodeMCU ESP8266 using the HX711 Load cell amplifier module. HX711 is a precision 24-bit analog to digital converter (ADC) designed for weighing scales and industrial control applications to interface directly with a bridge sensor. The HX711 load cell amplifier is used to get measurable data out from a load cell and strain gauge.
The electronic weighing machine uses a load cell to measure the weight produced by the load, here most load cells are following the method of a strain gauge, Which converts the pressure (force) into an electrical signal, these load cells have four strain gauges that are hooked up in a Wheatstone bridge formation.
We will make a Weighing Scale Machine which can measure weights up to higher-value like 40KG. We need to calibrate the load cell and find the calibration factor. Once the calibration is done, we can include that factor in our code. Thus this will make the scale precise and accurate. The greater is the mass the greater the error. So we will try to remove the error from the weighing scale. We will finally display the measured weight in the 16×2 I2C LCD Display. We will send the so obtained weight value on the IoT Cloud platform called Blynk Application. Thus, weight can be monitored from any part of the world simply by observation on the Blynk app dashboard.

So awesome, it's very easy to understand and make one myself! Thanks a lot! The project documentation is very well made. Can I suggest one little small update? You could explain that the device between the LCD and the ESP8266 is a I2C module on your breadboard and what does it do in the project.
Thank you Shradha! You are great
thanks for amazing description.
I want to connect the weight loading unit with the Arduino and when it reaches 1 kg, the LED works on one of the Arduino ports
Hi can you please teach me how to make a GUI on Microsoft visual studio where i can receive the weight being applied on the load cell?
in the arduino code how was the baud rate in the serial.begin() determined? for the esp8266 we need 9600 and for hx711 we need 57600
which load cell to be used in order to measure weight greater than 40?
and will it be able to interphase with nodemcu
2 questions.
Is there a way to do use Bluetooth instead of wifi?
If I have a Bluetooth scale currently (renpho model) is there a way to pack sniff the signal and pipe it into a custom app?
Hi Please ,,,, can you demonstrate how to get this done with new Blynk platform ,
Voice over is really good 👍😌 Anyway, very useful IoT based Project. Keep sharing more..
Thanks, will keep you updated with more such stuff.
Can the weight function be converted to count of items ? Hopefully the answer is yes and in that case what’s the update on the code ?
can i build this system with 4 loadcells? The critical factor here will be different weights in 4 loadcells. These weights will be displayed separately or in total on the phone or LCD display.
hey can i know what HX711 you use in schematic diagram fritzing ? i cannot find it
Can you please tell me what software did you use to simulate it? Or which software can I use to simulate it?
hi thank you for the helpful video. I have followed all your steps but my load cell keep giving 0.00kg reading. can you help me? thank youu
What is the accuracy and precision of this scale
What is the input component for this Weighing Scale?
Once again thanks for this amazing and informative video in a lovely voice over😍😍🔥🔥
Thanks bro, keep supporting.
@@HowtoElectronics l want buy thise project, cane u send me, how much prise, please reply
Здравствуйте, отличный проект, нужно ли прошивать nodemcu прошивкой для работы с hx711 и какой?
Bhaiya can you make one project which is automatic stair case in when a person keep his feet on the first steps of the stair the staircase should produce a song of sa, re, ga, ma, pa, dha,ni like this the. Sounds comes out.. So how can we make this model ??
Awesome iot project.... and the voice is to goods..
Thanks for appreciation
Sir can we use this project for Saline Bottle Monitoring system ??
May i know how much power sources you used?
How many of load cell i can connect with node mcu
wanderful project
Привет, как можно реализовать сброс на ноль с blynk? 'что поменять в коде?
Good day, I know this is an old video, but would it be possible for you to make an updated version of this using 4pcs Human Scale Load Cell Weight Weighting Sensor 50KG Half-bridge, it would really be a great help to my Grade 8 Son, He doesn't have any prior knowledge of Arduino, but He is thinking of a somewhat similar project for his research paper in school, but he needs a design somewhat similar to a bathroom scale, with remote connectivity via Bluetooth or Wi-Fi. With a working sample It would be easier for him to learn and analyze what and how it works. Unfortunately, I also don't have any knowledge of Arduino so I can't teach him what to do. Thank you and hoping you still have time and chance to update this.
What if i want readings in gram or oz
Nice project
which simulation do you use
may i know the simulator you use ?
Very nice project and very sweet voice. Nicely explained
Thank you
Hii
What's the minimum weight it can sense?
Great sir
Sir can i save this value Anywhere like in memory card
Again with this lovely voice..!!❤
Thanks for good feedback

how much this project will cost mam? nice video
Lovely voice.❤
How I slove it
Can i get source code and gerber file plz
Hi can you help me with a project?
Theri problem for hx711library
I have all these things and now i have applied your code but the weight is not changing on the display on putting any weight on scale
🙏🙏🙏please reply🙏🙏🙏
I also have the same problem please tell 🙏
I cannot move further after selecting baud rate to 115200. After selecting it is still blank. Please assist me
U have to make the Serial.begin(115200);
How did you get the calibration factor? -109525, how do I know the exact factor for my 5kg load cell? Someone please explain me
Yess i need help with this too , have you made the model?
@@sarahkhalid1148 you can find sample code on sparkfun website, firstly calibrate with known weight..
Can you give me code
Which industrial sensor can be used to measure more than 200 kg?
There are few load cell with weight higher than 200 kg. You can use those.
Thanks
Nice one bhai
Thanks
Please send code and diagram
What's is your name?
Can you please connect me on this project. I have a requirement for this
Hello, sent an email, but no response!
THE CODE IS SHOWING ERROR WHEN COMPILED IN ARDUINO IDE. ANYONE FACING SIMILAR PROBELM??
Hey man, could you send me the proggram please?
ciao, vorrei costruire una bilancia per le mie api, cosi saprei in tempo reale quando andare ad aiutarle per non morire di fame 😞😞😞 mi piace il tuo progetto e penso che sia molto valido per il mio progetto… potresti inviarmene un prototipo? (cosi potrei replicarlo per tutte le mie arnie) pagherei per i costi dei pezzi e spedizione … ti ringrazio in anticipo 🙏🏻🙏🏻
If you watch the video more than 2times gather here please
Parla piu piano per favore
