During the COVID-19 pandemic, Unilever aimed to ensure the health and safety of employees working in their manufacturing facilities. To address this, Unilever developed an IoT-based system for monitoring employee body temperature and maintaining social distancing protocols. The system involved integrating GPS technology into employees' identity cards or smartwatches to track their location and ensure a minimum distance of 2 meters between them. Alerts were generated for the employees’ reporting managers if any safety protocols were violated.
