I need to measure distances where IR would not be possible. I need to measure approx from 20ft to 300ft accurately. I am trying to decide which would give the easiest circuit design and highest accuracy without interference? I plan to use a micro controller for the project.
Edit, to define accuracy, +/- 1" would be just fine. Possibly even a little looser would still work.
