bathroom entry and soap dispenser detection
DESCRIPTION
Bathroom Entry and Soap Dispenser Detection. Paul Chang, Joe Contreras, Alejandro Gari Georgia Tech ECE4007/L03 October 22, 2009. Did you know?. In industrialized nations, up to 30 percent suffer from food contamination - PowerPoint PPT PresentationTRANSCRIPT
• 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 bacteria2
• System to track employee hand-hygiene
• Reduce the chances for food contamination
• The system is being designed for Arby’s
• The cost of the system is $1,730
3
• Detecting entry and exit of employee
• Detecting use of soap dispenser
• Logging of RFID tag data
• Real-time alarm
• Targeted for food service industry
4
• Have employee wear tag
• Place antenna near entrance
• Use IR sensor to detect soap dispensing
• Create data logs through C program

• Employee opens door but then decides to not enter the bathroom
• Employee uses restroom for more than fifteen minutes
• RFID tag is detected but employee does not enter bathroom and decides within 15 minutes to enter
11
• Component CommunicationsRFID tag and IR sensor communications with eBox will be verified
• ProgramScenarios will be tested to achieve a desired success rate of 80 percent
• SimulationA simulation of the entire system will be
performed prior to release of the product
