Abstract

The IoT-Based Smart Street Lighting Monitoring and Adaptive Control System is an intelligent urban infrastructure solution developed to optimize street lighting, reduce energy consumption, and simplify maintenance operations. The system consists of a street model containing four LED street lamps, each equipped with a dedicated IR sensor for vehicle tracking and an individual LDR sensor for lamp health monitoring. An additional IR motion sensor positioned at the entrance of the street detects approaching vehicles and initiates intelligent sequential lighting. The embedded hardware utilizes an Arduino Nano for real-time sensor acquisition and street light control, while an ESP32 manages wireless communication between the hardware node, custom IoT server, and mobile monitoring application. As vehicles travel along the street, individual lamps illuminate sequentially based on sensor feedback, ensuring energy-efficient operation without compromising road visibility. Every ESP32 node is configured with its geographical location during installation, allowing each street to be uniquely identified on the monitoring platform. The system continuously uploads traffic activity, lamp status, fault conditions, and operational data to a custom Flask-based IoT server with an SQLite database. A mobile administration application enables authorized users to remotely monitor street conditions, identify faulty lamps, and perform maintenance planning efficiently. Designed as a scalable smart city prototype, the project integrates embedded systems, IoT communication, cloud monitoring, and intelligent fault detection into a unified street lighting management solution.

Project Description

Traditional street lighting systems operate continuously throughout the night regardless of traffic conditions, resulting in unnecessary energy consumption and increased operational costs. In addition, identifying faulty street lamps often requires manual inspection, making maintenance inefficient and time-consuming. This project introduces an IoT-Based Smart Street Lighting Monitoring and Adaptive Control System that intelligently controls street lights according to real-time vehicle movement while continuously monitoring lamp health and traffic activity. The demonstration model consists of four street lamps installed along a road segment. Each lamp contains an LED representing the street light, an individual IR sensor positioned near the lamp for vehicle tracking, and an LDR sensor placed to verify whether the lamp is actually producing light. Another IR motion sensor is installed at the entrance of the street to detect approaching vehicles. When a vehicle enters the street, the entrance IR sensor detects the movement and activates the lighting sequence. As the vehicle moves forward, the Arduino Nano continuously processes input from each IR sensor and turns ON the corresponding street lamp while turning OFF lamps that are no longer required. This sequential lighting mechanism minimizes unnecessary power consumption while maintaining safe visibility along the road. To ensure reliable maintenance, every street lamp includes an LDR sensor that continuously monitors the actual illumination produced by the LED. If the controller commands a lamp to turn ON but the LDR detects insufficient light, the system identifies the lamp as faulty and immediately reports the fault to the IoT platform. This enables maintenance personnel to identify defective lamps without performing manual inspections. The complete hardware communicates with a custom-developed IoT platform through an ESP32 module. The Arduino Nano manages all sensor inputs and output devices, while the ESP32 is dedicated to wireless communication, cloud synchronization, and data transmission. During installation, every ESP32 node is assigned its geographical location coordinates, allowing each street lighting controller to be uniquely identified on the monitoring dashboard. This enables administrators to easily locate the physical installation of each street and quickly identify the exact location of faulty lamps. A custom IoT server developed using Flask, SQLite, and Tailwind CSS stores all operational data, including traffic activity, lamp status, fault reports, and historical events. A dedicated mobile application provides administrators with real-time monitoring, allowing them to view street status, identify malfunctioning lamps, monitor traffic patterns, and plan maintenance activities efficiently. The complete system is designed as a modular PCB-based prototype combining embedded electronics, IoT communication, cloud infrastructure, and intelligent monitoring into a scalable smart city solution.
