False Triggering

[inventabuild]

I have four fsr's set up on a flat surface w/ a flat glass plate on top of them and I'm running 2 sets of 2 ea fsr connected in parallel or a total of 4 ea frs. The resistance I measured in the wires attached to the fsr's ranges from 160K to 240K ohms.

1. Do I need to lower the sensitivity of JohnSL board to prevent false triggers?
2. Can I add 500K ohm resistor in series with the fsr's to help prevent false triggers?

Please advise. Thank you.
