Abstract

Energy usage connected with conventional lighting systems is a critical problem in residential and commercial
spaces. The purpose of this paper is to develop and experimentally evaluate an Internet of Things (IoT)-based
smart lighting system that incorporates adaptive illumination control, Bluetooth Low Energy (BLE)
communication, and resonant wireless power transfer in one system. For experimental testing, the developed
system was built using an ESP32 microcontroller, a TSL2561 digital light sensor, an NRF52832 BLE module, and
a power switch circuit that operates with the use of MOSFET. During experiments, energy efficiency, control
responsiveness, and wireless power transfer performance were estimated. The developed smart lighting system
provided 30% energy savings compared to a conventional relay-based lighting system. BLE commands' processing
was characterised by 0.5s of average response time and a 95% success rate within 10 m range. Additionally, the
wireless power transfer subsystem ensured an energy transfer efficiency of approximately 85% at a distance of 10
cm.
