I found what is causing the crash however I do not know why its crashing.
The issue is pressure = bmp.readPressure(); line of code. Any help would be greatly appreciated

need something like this in your setup..

  if (!bmp.begin()) {
	Serial.println("Could not find a valid BMP085 sensor, check wiring!");
	while (1) {}
  }

good luck.. ~q

That was the issue. Thank you for the help
