Hello!
I am fairly new to the Arduino platform, however I do have some experience from years past.
I am looking for help in fully understanding exactly what I need for a future project.
The project involves multiple (say 10+) strain gauges mounted on steel tubes to measure strain, then from that, to get internal stress in the tubes in real time. Ideally, the program would be set up to alert me if any one of the tubes is nearing yield stress of the material.
I understand that I will need a signal amplifier, such as an HX711 amplifier, for the signal coming from the strain gauges.
Here are a few questions that I am looking to have answered:
1. Can one Arduino board handle that many strain gauge inputs, and if so, what board would the ideal one?
2. Will I need a separate HX711 for each strain gauge input?
Thank you very much for your help!
