The Flexiforce Pressure Sensor is essentially a variable resistor. When no pressure is applied, the resistance between the two outer leads is incredibly large, probably greater than 10 Mega Ohms (more than my meter can measure). When pressure is applied, the resistance measured between the outer leads lowers until you’ve reached the max pressure it’s intended to measure. In this case that’s about 25 lbs of pressure, and the current Flexiforce Pressure sensor I’m using measures about 50K Ohms when given that max amount of pressure.

You can test the range of your sensor using a multimeter. Just attach the two outer leads to the multimeter and set the meter to measure resistance. Then squeeze the sensor and watch the resistance value change.

Now, let’s read values with an Arduino. To do this, we create a voltage divider circuit with the Flexiforce sensor and an extra resistor. I picked 1M Ohm in this example because it’s about in the middle of the Flexiforce sensor’s dynamic range. Many other similar values could work as well.

Connect 5V to one side of the voltage divider, and GND to the other. In the middle, where the Flexiforce sensor and the resistor connect, connect one of the analog-in pins of the Arduino with a jumper wire. In this case I used pin A0. Here is a Fritzing diagram of the setup:
