Yes; however, you will need some additional electronics to do so. For the Craftsman 1/2 HP garage door opener I have, I'd need a signal generator that sends a pattern of 6-millisecond-long 6-volt pulses, followed by no signal for 0.5 milliseconds. This needs to match the signal the sensors send so the garage door works normally. This will vary by model, and it requires an oscilloscope to verify. It may be easier to just tape the sensors together so nothing gets in the sensor's path.
