Smart IOT-Based Street Light System for Sustainable Cities

Abstract

A sustainable smart street lighting system for urban areas that combines IoT technology with renewable energy sources is presented.  Street lights with PIR and LDR sensors are controlled automatically by the system using ESP32 microcontrollers based on motion detection and ambient light intensity.  Energy efficiency is greatly increased thanks to a hybrid energy system that combines solar panels and Savonius wind turbines.  A lead-acid battery stores electricity for use at night, while an MPPT controller maximizes solar energy collecting.  In addition to promoting sustainable urban infrastructure, the system guarantees decreased energy usage and operating expenses.
