The Problem
Counting foot traffic in event spaces without additional / overhead rigging.

The Solution
Proximity sensors to detect when a threshold is crossed with a little logic to filter out people standing in front ot it. In a real world scenario each of these sensors would talk to the cloud and response with events and an ID, all the data could be aggregated to determine trends and help plan for better traffic at the next show.
