Kode:

const int dry = 595; // value for dry sensor
const int wet = 239; // value for wet sensor

void setup()
{ 
Serial.begin(9600);
}

void loop()
{
int sensorVal = analogRead(A0);

// Sensor has a range of 239 to 595
// We want to translate this to a scale or 0% to 100%
// More info: https://www.arduino.cc/reference/en/language/functions/math/map/
int percentageHumididy = map(sensorVal, wet, dry, 100, 0);

Serial.print(percentageHumididy);
Serial.println("%");

delay(100);
