Comment on Overengineering a way to know if people are in my university's CS labComments−TrackerFF1yMy first thought was to put some motion sensors inside the room, along with a sensor for the door (open/closed), as well as some sensor for counting the people walking through the door. Maybe even some co2 sensor to detect changes.
