The sensors report a higher value when the item is closer, and lower value when further away. They are hall-effect sensors. Can you provide me with more info into triangulation?

I have 3 sensors I know the distance between. They report to me 0.58V when no change is found and when a change is found they report .64V .79V .66V for example. Would it be possible to locate the point where the item is?

I gave them a call, the impression I got is I would need a huge order and is far more expensive than the FlexiForce. How is weight mesuared in those cheap digital scales? I am sure those are accurate enough for my purposes.

Is there a alternative to the FlexiForce 1lb sensor. $20.00 a piece is rather high for my project, seeing how I will need multiple ones. Any ideas?

http://grab.by/Sqy For a glass replacement I have notecards or some bendable object that makes contact with two conductive surfaces, that I can measure the resistance between. Cooper doesn't have enough measurable resistance as far as I know. The end project is a "touchscreen".

I am attempting to create a line (5" long by .5") that I can then measure the resistance between. I have tried creating a paint/ graphite mix but no matter what consistency I make by diluting it with acetone, I can't get a accurate distribution of values. They jump erratically when I measure them.
