This method is actually suitable for measuring speed and acceleration. With the 3D printed casing we are able to improve the measurement accuracy. It gives us more precise trigger points. We may need to adjust the sensitivity of the infrared sensors on the racetrack, which is why the housing is easy to open and close.
