Project Overview¶
We designed a device to track the usage of a hallway. Using one sonar sensor it tracks how many people have walked in the hallway and which direction they were going. This information could be used by companies to keep track of what areas of a building are used more often while not collecting user data. It is an accurate and anonymous data collection method.
Hardware¶
