I am a hobbyist software developer as well electronic hobbyist. Sensoring RPM with a camera is possible but it surely don't need to run with a game engine (Unity). Make a proper app with code base, it gives more control and more possibilities than doing it with Unity.

Hi, Sorry for not having a great experience withTachometer - RPM measuring app. It is designed for phonographes or rotarty devices to measure rotational speed with smarth phone sensors. In order for the app to make measurement, it must return with the rotating device.
