An IoT-based Wireless Sensor Network for Lighting Control Systems

The fifth industrial revolution brings the focus to well-being, sustainability, and resilient human-centric manufacturing systems. To this end, the quality and quantity of light in the work environment plays a fundamental role for the management of the human body’s circadian clock, and hence for the psychophysical well-being of the worker. In this work we propose a lighting control system based on a wireless sensor network able to realize an architecture fully compliant to the Internet of Things requirements, and an inclusive work environment focused on worker’s physical and mental well-being. In particular, an ad-hoc node with suitable interface has been developed to interoperate with standard lighting control systems and to extend their functionality to remote monitoring through web platform. The proposed solution has been tested in a critical scenario such as the industrial one in which the performance of the proposed wireless sensor network has been analyzed in terms of Round Trip Time, packet loss and goodput. The obtained results show that the value of the work is its versatility and scalability relatively to the number and density of nodes, network typology and sensing units.
