I am trying to start a home project with a raspberry pi. I want to link a number of these force-sensitive resistors up

square force resistor

The issue is i really want to assign some form of id so i can tell which has been triggered. Can you get sensors with this ability or is there someway i can add a chip or something :$

I literally have no idea and am just messing about at home - so hopefully someone can lend some helpful advice!

Do you need analog input on how much force is applied, or merely an on-off indication as suggested by your use of the word "triggered"? –  Anindo Ghosh Oct 18 '13 at 10:47
    
no all i need to determine is whether the sensor has had pressure added or not –  Biscuit128 Oct 19 '13 at 16:39

One way is to add a multi channel ADC chip with enough channels for all your FSRs

One example, using the 8-channel MCP3008, is shown in this Adafruit tutorial which mentions FSRs.
