โมดูลเซนเซอร์ FSR402 Force Sensitive Resistor 0.5 inch FSR US

โมดูลเซนเซอร์ FSR402 Force Sensitive Resistor 0.5 inch FSR US 

Description

FSR is one Force Sensitive Resistor, allowing you to detect the physical pressure, extrusion, and weight.They are simple using, low cost.

FSR is delimited by two layer, as the pressure increases, the activity of these elements point will touch the semiconductor, making resistance smaller 

Code Example

/* FSR simple testing sketch.

Connect one end of FSR to power, the other end to Analog 0.
Then connect one end of a 10K resistor from Analog 0 to ground

int fsrPin = 0; // the FSR and 10K pulldown are connected to a0
int fsrReading; // the analog reading from the FSR resistor divider

void setup(void) {
// We'll send debugging information via the Serial monitor
Serial.begin(9600);
}

void loop(void) {
fsrReading = analogRead(0);

Serial.print("Analog reading = ");
Serial.print(fsrReading); // the raw analog reading

// We'll have a few threshholds, qualitatively determined
if (fsrReading < 10) {
Serial.println(" - No pressure");
} else if (fsrReading < 200) {
Serial.println(" - Light touch");
} else if (fsrReading < 500) {
Serial.println(" - Light squeeze");
} else if (fsrReading < 800) {
Serial.println(" - Medium squeeze");
} else {
Serial.println(" - Big squeeze");
