I'm a college student on a team that is building a BalloonSat, and we want to use strain gauges for our experiment. We will be testing the strain induced by the near space environment on a small piece of 3d printing plastic using an Arduino Uno, one gauge on the x-axis, and another on the y-axis. I've done some research already and know I'll need to use a wheatstone bridge circuit for the gauges, and a micro volt amplifier to make the small changes in resistance readable. How should I go about choosing gauges and a microvolt amplifier?
Thanks for your help.
