Overview
Overview
In libraries or large study spaces, finding a seat may be challenging for those looking for a space to work or study. With this board, we'd like to be able to monitor which seats are available and which are occupied. We aim to replicate the capabilities of some smart parking garages that monitor how many spaces are open on each floor so you don't have to waste time finding a spot yourself.
