Monitoring Restaurants in Real-Time

Consumers in developed countries are wasting an estimated 222 million tonnes of food products per year, and most of the waste is produced at restaurants. The brazilian health regulatory agency: ANVISA requires that restaurants are monitored by nutritionists. One of their tasks is to control the temperature of food preservation to verify compliance with ANVISA regulations. For restaurants to avoid food waste and work within these regulatory standards, an efficient management is needed to streamline internal processes and to make more accurate decisions. The objective of this work is to create an intelligent software to monitor the quantity and temperature of a self-service restaurant buffet in order to minimize food waste, improve the handling of nutritional information and optimize the restaurant management. The system should be able to check the temperature and the consumption of food presented in buffet vats (also know as gastronorm) and make data available to relevant restaurant divisions like cooking, nutrition and real-time management. The system is created using resources of IoT, Edge/Fog and Parallel/Distributed computing. Node-red, ThingSpeak and Arduino IDE compose the technology framework .
