Hi I am working on a project for school and would like to use an arduino to connect 3 120Ohm strain gauges to my computer and display a live graph and data. The reason for 3 strain gauges is because I am trying to measure the strain on a barbell so using 3 strain gauges eliminates any issues with the barbell rotation. I have read that I will need to use a amplifier, but most amplifiers I have found require 4 wire strain gauges.
The strain gauges I will be using are
What are my best options to achieve this? I am brand new to Arduinos but have been told it is a great way for me to set up my project.
Any suggestions or information is greatly appreciated
