It's the first time a post something here so I hope I do it correctly.
A friend of mine asked to help him designing a system to weight a small silo that contains cereals using load cells. I tried to search a bit online but could not find many resources about it.
We would like to use 6 compression load cells; each load cell should go under a silo's "foot", the silo has 6 feet (it looks like this one).
We would like to connect the load cells to an arduino board, using the HX711 Amplifier.
I have never done anything similar, but I think we should connect the load cells in parallel, following something like this tutorial. The problem is, that most of the tutorials/boards I have found supports up to 4 load cells, how can I do it with 6? I though maybe using more of those cell-combinator boards, but I'd like to have some insights on this.
Also, this is the load cell spredsheet:
As you can see, the excitation voltage is not specified (up to 15V) and the output is 1mV/V, do you think it's compatible with the HX711?
Any other input on the project is more than welcomed, as I am a newbie.
Thanks for the attention and sorry for the long read!
