    FSRs are sensors that allow you to detect physical pressure, squeezing and weight. They are simple to use and low cost. This sensor is a Interlink model 402 FSR with 1/2 diameter sensing region.

    FSR's are basically a resistor that changes its resistive value (in ohms Ω) depending on how much its pressed. These sensors are fairly low cost, and easy to use but they're rarely accurate. They also vary some from sensor to sensor perhaps 10%. So basically when you use FSR's you should only expect to get ranges of response. While FSRs can detect weight, they're a bad choice for detecting exactly how many pounds of weight are on them.

    FSRs are made of plastic and the connection tab is crimped on delicate material. The best way to connect to these is to simply plug them into a breadboard or use a clamp-style connector like alligator clips, female header, or a terminal block. It is possible to solder onto the tabs but you must be very fast because if your iron is not good quality or you dally even a few seconds, you will melt the plastic and ruin the FSR! Don't attempt to solder directly to your FSR unless you are absolutely sure you have the skills to do so.
     
    Simple project with the sensor :

    analog input by reading an analog sensor on analog pin 2 and

    turning on and off a light emitting diode(LED) connected to digital pin 13.

    The amount of time the LED will be on and off depends on

    the value obtained by analogRead().

    The circuit:

    *the 

    * center of the sensor and resistor circuit is connected to analog pin num2

    * one side pin (either one) to ground

    * the other side pin to +5V

    * LED anode (long leg) attached to digital output 13

    * LED cathode (short leg) attached to ground


    Arduino code :


    int sensorPin = 2; // select the input pin for the potentiometer

    int ledPin = 13; // select the pin for the LED

    int sensorValue = 0; // variable to store the value coming from the sensor


    void setup() {

    // declare the ledPin as an OUTPUT:

    pinMode(ledPin, OUTPUT);

    }

    void loop() {

    // read the value from the sensor:

    sensorValue = analogRead(sensorPin);

    // turn the ledPin on

    digitalWrite(ledPin, HIGH);

    // stop the program for <sensorValue> milliseconds:

    delay(sensorValue);

    // turn the ledPin off:

    digitalWrite(ledPin, LOW);

    // stop the program for for <sensorValue> milliseconds:

    delay(sensorValue);

    }
