FORCE PRESSURE SENSOR

                                                                   A Force pressure sensor is used to sense the force. A force-sensing resistor is a material whose resistance changes when a force, pressure or mechanical stress is applied. They are also known as "force-sensitive resistor" and are sometimes referred to by the initialize "FSR".  Force Sensing Resistors (FSR) are a polymer thick film (PTF) device which exhibits a decrease in resistance with an increase in the force applied to the active surface. Its force sensitivity is optimized for use in human touch control of electronic devices. We can interface force pressure sensor with Arduino to detect the force present.

Application:

• Detection of force.
• Measurement of higher loads.
• Stable output with respect to load area.

Sample Project With Arduino:

                                  In this we going to turn ON the LED whenever the force or pressure is detected by the force pressure sensor.

Materials required:

• Force pressure sensor
• Arduino UNO
• LED 
• Jumper wires

Circuit:

Code:

int sensorpin = 7;

int LED = 13;

void setup() {

  Serial.begin(9600);

  pinMode(sensorpin, INPUT_PULLUP);

  pinMode(LED, OUTPUT);

  digitalWrite(LED, LOW);

  Serial.println("Force / Pressure Sensor");

}

 

void loop() {

  if(digitalRead(sensorpin) == LOW)

  {

    Serial.println("Force / Pressure Happened");

    digitalWrite(LED, HIGH);

    delay(500);  }

  else  {

    digitalWrite(LED, LOW);
