How can I detect every time a sponge ball hits a wall?
I need to monitor the frequency that a ball hits a wall and bounces off. The wall is bright and the ball is red - size of a clown nose.
Are there microwave/LED/Laser or other kinds of motion detectors that can monitor impact on a surface?
The ball is not going to make any kind of noise when hitting the wall, hence acoustic monitoring is out...
It partly depends on how the ball hits the wall.
If it is on a pendulum then what you need is the sort of detector that a domestic garage door has to stop it descending if something breaks the beam.
Otherwise if it is random you will need a fan laser and a series of detectors at the opposite side
These people might have something
