سنسور سنجش فشار مقاومتی RFP602

Resistive Force Pressure Sensor RFP602
Description
The idea of the pressure sensor test is to convert the stress applied in the sensing region , of the sensor film into a change in the two-line resistance value and acquire the external stress change information using the stress-resistance calibration curve.
Geotechnical engineering triaxial test earth pressure test, sample pressure distribution test, bionic robot foot underground sensing, mammalian biting force test biological investigations, and other industrial areas may all benefit from this device.
The RFP602 membrane pressure sensor measures static and dynamic pressure on any contact surface, and the membrane pressure sensor converts the pressure applied to the sensor detection area into a resistance (analog) signal.
Then, according to the force-resistance calibration curve, information about the change in external pressure is obtained. The higher the pressure, the lower the sensor output resistance.

// Define the analog pin used to read the pressure sensor
const int pressureSensorPin = A0;

void setup() {
  // Initialize serial communication for debugging
  Serial.begin(9600);
}

void loop() {
  // Read the analog value from the pressure sensor
  int analogValue = analogRead(pressureSensorPin);

  // Convert the analog value to pressure in kPa
  float pressure_kPa = analogValue * 0.2; // Assuming a linear relationship between analog value and pressure

  // Print the pressure value to the serial monitor
  Serial.print("Pressure (kPa): ");
  Serial.println(pressure_kPa);

  delay(1000); // Delay for 1 second
}

Connecting RFP with Arduino Uno

Resistive, piezoresistive force sensor (scale), which can measure up to 5KG on a disk surface of approximately 10mm, compatible with Arduino and other development boards.
The sensor is flexible and very thin.
It connects to the board without polarity, like a resistor, but needs a 10K pull down resistor between GND and the Analog pin.
See the picture below.
