Create a matrice of FSR sensor

Using Arduino Project Guidance
#1

Hi,

I want to create a matrice of FSR sensor like this one for example : Overview | Force Sensitive Resistor (FSR) | Adafruit Learning System

It's to create some kind of smart textile, I want it to be really thin so we can measure pressure in different area when we seat on it for example.

This sensor looks great but it would be too much wires since I need at least a matrice of 12x20.

What would be the best practice / sensor for that?

Thanks for your guidance

You’d also need 240 (or more) analog pins to read them. No Arduino has that many analog pins.

Thanks PaulS. Yes I am aware of this issue, this is why I'm wondering if maybe there is sensor that use 1-Wire or I2c instead?
