Predict the output of the following code if the object is moving towards the sensor.

int op = 6;
int isBarrier = HIGH;
void setup() {
pinMode(op, INPUT)
Serial.begin(9600);
}
void loop(){
isBarrier = digitalRead(op);
if (isBarrier == LOW) {
Serial.println("1+");
}
else{
Serial.print("clear+"); 
delay(100);
}
