I just want to point out though that your signal return, a.k.a the DigitalInput->Get() on the sensor will vary depending on which wire you put for the digital input, the Black (light out), or White(dark out), the code above would work for the white wire, Dark out, which will return 1 if it is on the line, and 0 if it is not. Good luck!
