This research unveils an avant-garde Cyber-Physical Street Lighting System leveraging Field Programmable Gate Array (FPGA) technology to orchestrate energy-efficient urban illumination. The system synergizes Infrared (IR) sensors, a Light Dependent Resistor (LDR), and a 7-segment display, orchestrated through a Xilinx Artix-7 FPGA programmed in Verilog using Vivado Design Suite. By integrating adaptive sensor fusion, the system dynamically modulates street light activation based on ambient luminosity and spatiotemporal motion detection, achieving unparalleled energy optimization. The LDR employs a threshold-based algorithm to discern diurnal transitions, while IR sensors utilize differential signal processing to track vehicular and pedestrian dynamics, triggering illumination only during low-light conditions with detected activity. A 7-segment display delivers real-time analytics, visualizing motion event counts to facilitate diagnostic telemetry. The FPGA’s parallel processing prowess, coupled with its reconfigurable architecture, enables high-speed, low-latency control, surpassing traditional microcontroller-based paradigms. Advanced features include frequency-divided clock synchronization for precise timing and modular Verilog constructs for scalable design. This solution pioneers smart city infrastructure by reducing power consumption by up to 60\% compared to conventional systems, as validated through Vivado simulations and hardware synthesis. Its robustness against environmental perturbations and compatibility with IoT ecosystems underscore its transformative potential. Future enhancements envisage radar-based sensing, photovoltaic integration, and edge-AI analytics for predictive maintenance, positioning this system as a cornerstone for sustainable urban ecosystems. This work not only redefines intelligent lighting but also exemplifies FPGA-driven innovation in cyber-physical systems.
