The current situation with COVID-19 is changing our courses of action toward ensuring health security . This is particularly crucial in airports, which usually receive more than 300,000 travellers in one single day . In this work, we present an Internet of Things (IoT) network to monitor the status of toilets and improve their maintenance . The system is based on IoT networks with different sensors to control soap levels, room capacity, distances, temperature, and humidity . This information is processed by a multi-agent system that detects possible anomalies and makes decisions accordingly . A case study in a real environment is developed in order to demonstrate the usefulness of the system . The results show that the proposed method can be used to successfully manage and control airport toilets.
