Looking to design a system that can detect an object tethered at 52 feet traveling 100 mph ( on half a hemisphere) and signal when the object moves more than 2 feet inside or outside the path. System will only have a max of 11.1v and weight is critical, no more than 15 grams total system.
Reading through some of the forums ultrasonic looks like an option but the sensors I am finding commercially are good for -500mm. Can I measure from the tether anchor and just relent from the moving object?
Hoping the group has some ideas to get me moving in the right direction.
Thanks -Lester
