analog serial read values are not equal
Try something like this

void loop() {
  // read the input on analog pin 0 and 1 with delays for stability:
  delay(1000);       
  int sensorValue1 = analogRead(A0);
  delay(1000);        
  int sensorValue2 = analogRead(A1);

  // print out the value you read:
  Serial.print("val1 = " );
  Serial.print(sensorValue1);
  Serial.print(" val2 = " );
  Serial.println(sensorValue2);



 }
