get your self a steel wire cable about 30 to 35 feet long.
create a loop about 1and 1/2 feet in diameter by coiling the cable several times and leave a good 15 feet. (or however long you need it to reach plus a few feet so that you can throw it just passed the sensor)
You can use duct tape to hold every thing together.
Now just toss your device just passed the sensor and drag the loop over it.
Ahh, access.
