Are you tired of how overcrowded the gym is at CMU? What if you knew the best time to go?
The goal of this project is to retrofit sensors to the cardio and circuit machines in the CMU gym that can easily detect machine usage. This info flows to a website/app that students can check to know the best time to use the gym or even a specific machine.
