Connect a water sensor

This water sensor is fairly easy to connect this to your Arduino, the requirements are simply VCC (5v), GND and then connect the SIG to one of the Analog pins. In our code example this will be Analog 0.

Code

int analogPin = 0;
int led = 13;
int val = 0;

void setup()
{
pinMode (led, OUTPUT);
Serial.begin (9600);
}

void loop()
{
val = analogRead(analogPin);
if (val > 600)
{
digitalWrite(led, HIGH);
}
else
{
digitalWrite(led, LOW);
}
Serial.println(val);
delay (100);
}
