Innovation and Digitization of Solar Cookers Towards Sustainable Energy Management

Abstract

This chapter presents the digitization and supervision of a photovoltaic solar cooker using a Raspberry Pi Pico W microcontroller. The system collects meteorological and electrical parameters (voltage, current, power, efficiency, temperatures) in real time and automatically regulates the cooker's operation. Data, transmitted via the MQTT protocol, are instantly displayed on a Tkinter interface and archived in MySQL databases to ensure full traceability. The results show that the developed architecture enables: Real-time reception and display of data, Timestamped storage for individualized monitoring, Deferred visualization through an interactive web application based on Dash. This centralized and scalable solution provides a reliable tool for supervision, performance analysis, and adaptation of solar cookers to various contexts.
