IOT-BASED REAL-TIME SMART CITY MONITORING DASHBOARD

Abstract

Rapid urbanization has intensified challenges related to waste management, environmental safety, and efficient resource utilization in smart cities. This paper presents an IoT-based real-time smart city monitoring dashboard designed to enhance urban waste management and public safety through continuous sensing and data visualization. The proposed system integrates multiple sensors, including an infrared (IR) sensor for waste bin level detection, a light-dependent resistor (LDR) for smart streetlight status monitoring (LDR– SSL), and a gas sensor for early detection of hazardous gas leaks. Sensor data are collected via a microcontroller-based embedded system and transmitted wirelessly to a cloud platform using Internet of Things (IoT) communication protocols. A centralized web-based dashboard provides real-time monitoring, alert generation, and historical data analysis to assist municipal authorities in proactive decision-making. The system enables timely waste collection, reduces unnecessary fuel consumption, enhances public safety by detecting gas leaks, and improves energy efficiency through smart lighting insights. Experimental results demonstrate reliable realtime data acquisition, low latency communication, and scalable system performance. The proposed solution offers a cost-effective, scalable, and efficient approach for smart city infrastructure management and can be extended to support additional urban monitoring applications.
