Project Description:
*******
In today’s episode, you will learn how to make an IoT based digital weighing scale using ESP32 WiFi + Bluetooth module, HX711 amplifier board, a load cell, and the new Blynk V2.0.
Arduino and ESP32 are completely different controller boards. Arduino is a 5V compatible controller board while the ESP32 WiFi + Bluetooth module is a 3.3V compatible controller board. And this is the reason, the calibration value of the HX711 and Load cell that works with the Arduino doesn’t work with the ESP32 Controller board. For ESP32 we will need to repeat the same calibration procedure again and we will also need to reduce the speed of the ESP32 module.
Previously, I used the same HX711 amplifier board and the same 5Kg Load cell with the Arduino and explained the most basic things including, the mechanical setup, Load cell working mechanism, HX711 amplifier board technical specifications and its interfacing with Arduino, how to calibrate the HX711, and its programming.

Nice!
Can you add one set values that if load is less then 100 gm buzzer will on ...
Sir, what is 7805 components, please reply 🙏
How do I implement wireless connectivity on the PCB? I am working on a project where I want to connect some components via an NRLF24L01 to my ESP32.
You can watch my videos on nrf24l01.
does the type of EPS32 matters, I have fond that there are multiple versions of those
i cant get online in blynk, can you help me?
how can i use 2 off loadcell sensor as a pair? is it possible?
Hello brother! i am using HX711 10kg Load Cell i am getting the Raw data (Empty)using SPI communication. Empty Raw Data: 8290759,8290777,8290776,8290741,8290744,8290783,8290744,8290754,8290745,8290729. how can i calculate Raw data into grams? just i need calculation, so please kindly reply
Hello sir, i am doing a project on load cell. I wrote the correct code and the wiring is perfect but still im getting random values without any load. Please sir i need your help. Can i get your contact details please
What if we use more than 5 kg weight
You will still go through the same steps.
Wow , that's seriously genius, can you teach us , how to update the scale data to Google sheet with date and weight data ,
It's on the list. Soon I will do it.
Dude you missed out LCD display it seems, to read the scale reading without mobile ,
I explained it in previous video. You can add the OLED code from that video.
can you pl make an video how to update the scale data to Google sheet with date and weight datas
