Strain Gauge and HX711 break out board.

I am a mechanical engineer currently investigating the possibility of accurately measuring the strain within a mechanical member under load with an arduino. I am familiar with strain gauges, their theory, how to use them, and of the Wheatstone bridge setup.

To amplify the voltage readings I intend to use the HX711 breakout board (mainly because it is the only component locally available and I live in a country where it is very difficult, and expensive, to order components online).

Referring tho the Wheatstone diagram attachment:
E = Excitation voltage (input voltage)
e0 = output voltage

Is it possible to retrieve the mV reading from the HX711 board of the e0 parameter?

Is the HX711 sufficient for this purpose, or do I need to look at alternatives?

Any help will really be appreciated.
Thank you.

  1. Yes, many libraries for HX711 provides an output data in mV or raw binary, knowing reference voltage it's easy to re-calculate ether way binary to mV and vice versa.
  2. If you can, alternatives ads1232 is much better, on average 100x times more accurate and less noisy
