Re: Presentation on sensors in FIRST
All good stuff- thanks for putting this together!
One of the more troublesome aspects of selecting a rangefinder is not the maximum range that the sensor can detect, but the minimum. Inexpensive rangefinders seem to have a minimum range that is about 10% of the maximum range; often what you pay for in higher end range finders is a decreased minimum range. It should also be noted that while many rangefinders are linear in range (that is V=kr), some are approximately reciprocal (V=k/r), and others may have stranger response curves.
