IoT System for Catering Service in Hospitals

In hospitals, IoT has facilitated connectivity between patients and medical services using historical health data. However, its adoption in hospital catering services has been slower. This work describes the implementation of an IoT system with a three-layer architecture: the first layer collects data on patient diets and environmental conditions from the food warehouse, the second layer processes this information, establishing rules and converting raw data into valuable information, and the third layer stores the data in the cloud, presenting it in a web application. A functional system was obtained that meets the needs of catering service personnel and the hospital in which it was implemented.
