How do I connect two four-wire load cells to the HX711
Please help.
Best guess, based on the very limited information provided: by soldering two wires to each of two load cells. Four wires, two load cells, and it's connected.
What load cell?
If the loadcell is a raw strain gauge with 2 pairs of outputs then you would use a Half-Bridge circuit.

No experience with this, but I would just connect the two in parallel.
Load cell voltages should average each other.

Have you really just repeated your question word for word? E.g. instead of answering the questions you where asked? I hope you are not really a teacher ...
What is the model number of the load cell?
If those ar two identical cells:
Cell A : red +V , black -V
Cell B : red -V , black +V
Signal cables to inputs (A or B) on HX711 (polarity doesn't matter)
I guess u'll need 128x ampl. => use inputs A
As we dont know exactly info about your cells.. Check datasheet for color coding
@knut_ny
Two 4-wire load cells have four signal wires.

sorry... didnt see the white wire in OPs drawing
...
connect cells parallel
red: +V , black -V
signals cables (also parallel) to port A
I do not understand the answers that English is not my first language.
Could you please explain by drawing on my project project

I used this configuration and obtained good results. However, I did some adjustments to enhance the accuracy of my system. Thanks!
