Sample Arduino code for the SST Liquid Level Sensor

LiquidLevelSensor.ino

// Liquid level detection using an SST sensor
//
// When a liquid touches the tip of the sensor,
// an LED at pin 13 turns on.
// 
// Hardware:
//     Sensor    | Arduino
//  -------------|---------
//    Vs (RED)   |    5V
//   Out (GREEN) |   pin 7
//   GND (BLUE)  |    GND

// Pins
const int LIQUID_SENSOR_PIN = 7;
const int LED_PIN = 13;

void setup() { 
  pinMode(LIQUID_SENSOR_PIN, INPUT);
  pinMode(LED_PIN, OUTPUT);
  digitalWrite(LED_PIN, LOW);
}

void loop() {

  // Read sensor. If liquid touches the tip, the sensor will 
  // read 0V. Turn on LED if liquid is present.
  int isDry = digitalRead(LIQUID_SENSOR_PIN);
  if ( isDry ) {
    digitalWrite(LED_PIN, LOW);
  } else {
    digitalWrite(LED_PIN, HIGH);
  }

  delay(200);
}
