Flexiforce Pressure sensors - does anyone have any experience with them?

i using 1 project, , realized not spit out linear values in serial monitor.

for example, weight of 1 pound may read 256, 2 pounds @ 459 , 70 pounds @ 879 on 1023 scale (this 100 pound sensor)

this current code map down 0-100 values

  int pressure = analogread(a0);
  pressure = map(pressure,0,1023,0,100);
  serial.println("pressure reading: ");
  serial.println(pressure);


is there way make 1 pound = readout of 1 sensor? how calibration work?thanks.

the best bet use google find information on them. don't think accurate.
