- Leader français dans le domaine de l'équipement de Grandes Cuisines et cantines scolairesFood Waste Weighing SystemPUBLIC SECTOROctober 2023 - Today (2 years and 10 months)Grenoble, FranceThe project's objective is to develop a complete "End to End" solution for **weighing waste in schools**. This new technology is currently being integrated into my client's catalog.This application will allow school cafeteria managers to automatically obtain, day by day, the quantity of food wasted in all the cafeterias under their responsibility. They will be able to generate tables that they can integrate into their statistics and reports.I was entrusted with defining the architecture and then developing the entire solution.The system consists of the following 3 main components:Data Acquisition: Development of a dedicated electronic board capable of managing 3 scales simultaneously. Data transmission by radio to a gateway (Zigbee technology).Data Recording and Cloud Transmission: Development of a gateway based on a Raspberry Pi4 implementing GPRS, Wifi, and Zigbee links. Implementation of a user interface for local configuration and administration.Cloud Server and API: Definition of a secure API for accessing Cloud data for WEB developers and development of a graphical application allowing end-client managers to download data in CSV format.The application is currently being deployed on pilot sites.
