Description

Buffet tracker is a system that tracks eating behavior at a buffet style restaurant. By tracking plates using RFID and linking them to a change in weight at a particular vessel we can infer the contents of each individual plate and analyze bulk trends in eating behavior.

Details

The system consists of a network of RFID and weight sensor pairs for each serving vessel. RFID tagged plates are picked up by restaurant patrons which are tracked from vessel to vessel. A Raspberry Pi pushes the data to a database on the cloud for analysis.

Research Value -

Look into bulk trends in behavior inside the restaurant setting
Objectively measure the food content of each individual plate taken to the serving area
Quantitatively measure the exact weight of food taken from each serving vessel
Non-obtrusive to the individuals, system can be completely hidden

Data Analysis[Sample] -

Components

1 × Arduino Uno Slave device for collecting and pushing sensor data asynchronously to the host.
1 × ID-12 RFID reader 125Khz RFID reader for identifying plates.
3 × 125Khz RFID tags Used on a per plate basis for identification
1 × Raspberry Pi
