In industrialized nations, up to 30 percent suffer from food contamination In the US, 76 million people suffer and 5,000 die annually from food contamination Within 12 hours, one bacterium that splits itself every half hour can create 17 million bacteria 2

System to track employee hand-hygiene Reduce the chances of food contamination The system is being designed for Arby’s The cost of the system is $1,730 3

Proposed ObjectivesFinal Design Objectives Detect entry and exit of employee Detect use of soap dispenser Logging of RFID tag data Real-time alarm Targeted for food service industry Detects entry of employee Detects when soap is dispensed Logs of soap or non- soap usage Targeted for food service industry 4

Have employee wear ankle bracelet, with RFID tag Place antenna near entrance at floor level Use Motion sensor to detect entry Use IR sensor to detect soap dispensing Create data logs through C program 5

Restarting the Program to wait for next employee. Employee is still in the restroom when a timeout occurs 12

Component Communications RFID tag, IR sensor, and Motion sensor communication with eBox will be verified Program Scenarios were tested and achieved a desired success rate of 80 percent Simulation A simulation of the entire system was performed and is functioning 13

Fix computer code so that program can restart properly after employee exits bathroom. Expand design for multi-personnel restrooms. 14
