I've seen this force plate from Vernier and it requires another USB interface device. They have an SDK that will they allow us to communicate with the force plate.
Is there something that I can create on my own that also measures weight? I think that I've seen a strain gauge thread on this forum.
There's this load sensor from Sparkfun (mentioned in thread) but it maxes out at 125lbs.
I essentially want to create a plate for someone to step onto and be able to measure their weight.
