Arduino Water Detection Alarm

SOURCE CODE:

const int waterSens = A0;//define water sensor to pin A0 const int speaker = 8;//define speaker to pin 8 int SensorValue;//create sensor data variable

void setup() {

pinMode(speaker, OUTPUT);//set speaker as an output

pinMode(waterSens, INPUT); //set water sensor as an input }

void loop() { int sensorValue = analogRead(waterSens);//read the water sensor value if (sensorValue >= 50) { tone(speaker, 800, 800); delay(200); tone(speaker, 600, 800); delay(200); }//if the sensor senses water then play an alarm }
