(This is a repost from another thread)
My question is, does this library auto scale your loadcell values, so that you dont exceed the mV per Volt range? ( I dont know how to phrase it properly, I want to span my measured values. Meaning I want to have it only read 0 – 5kg or 0 – 3000kg depending on what I set the span value to)
To clarify, everything is working perfectly, and I have had it running for awhile for different application, my common problem I run into is that my values tends to drift after a few hours although the temp and load-cell stays the same with or without weight applied on the load cell.
My load-cells are configured through Wheatstone bridge configuration.
I am pretty sure that if I span it better that this problem could go away.
Thank you in advance!

Hi.
Don’t worry about that.
You can follow this tutorial: https://randomnerdtutorials.com/esp32-load-cell-hx711/

AFAICT a 5V supply is needed for the HX711 breakout board but the means that the signal lines will also be at 5V when for an ESP32 they need to be 3.3V.

both the calibaration and the weigthing are just saying random numbers

thnx!, the calibaration and the weighting are both just saying random numbers?

Make sure you select the right baud rate in the Serial Monitor.
In this case 57600.

Hi.
Make sure to install the library indicated on the tutorial.
