Ks0309 Keyestudio Thin-film Pressure Sensor (Black and Eco-friendly)

Description

This sensor adopts the new flexible nano pressure sensitive material with ultra thin film pad. It has the functions of water-proof and pressure sensitive. When the sensor detects the outside pressure, the resistance of sensor makes a change. So using the circuit, we can convert the pressure signal of sensing pressure change into the electrical signal output of corresponding change intensity. In this way, we can get the conditions of pressure changes by detecting the signal changes.

Connection Diagram

Sample Code

int s_pin = A0;
void setup()
{
  Serial.begin(9600);
  pinMode(s_pin,INPUT);

}

void loop() 
{
  Serial.println(analogRead(s_pin));
  delay(500);
}

Testing Result

Wiring well and uploading the code, open the serial monitor on Arduino IDE. Then, press the sensor with your hand, the value shown on the monitor is increasing, so the sensor works normally.
