FSR - Conductive foam readings Answered
I am making a prototype of a force sensitive resistor, and i am using, to old 97%kobber coins, metal sheet and a tiny piece of conductive foam that i got from a tv-repair shop.
The setup is not very good, but its a start, and i am planning the next move for better results...
Now... I want some decent understanding of how the readings work, and why I get these results..
First test, are written with black, and and as you can see it, has the same amount of space between 0-1kg and 1-2kg, but 2-3 and 3-4 changes to a very small space? Why is that?
Second question is, that i have used the x10, to read larger forces. 0-2,5kg and 2,5-5kg has same amount of space. Will the space decrease too, when getting further up the scale too?
- I know the conductive foam has its limits too, but just to be clear of my readings.
Thanks in advance!
I hope you can see the readings on the picture..!
