Water Sensor with Arduino Nano

SOURCE CODE:

const int waterSens = A0; //define water sensor and set to pin A0 const int led = 9; //define led and set to pin 9 int sensorVal;//create a sensor value variable

void setup() { Serial.begin(9600);//begin the serial monitor pinMode(led, OUTPUT);//set the led as an output

}

void loop() { int sensorVal = analogRead(waterSens); //read the water sensor data

if(sensorVal > 200){//if the sensor senses water digitalWrite(led, HIGH);//turn the led on } else{ if //it doesn't digitalWrite(led, LOW);//turn the led off }

Serial.println(sensorVal);//print the data to the serial monitor

}
