With the rapid growth of urbanization and the increasing number of vehicles on the roads, air pollution has emerged as a major environmental concern. This project proposes an IoT-based Vehicle Emission Monitoring System that enables real-time detection and analysis of vehicular emissions. The system uses sensor modules to continuously measure concentrations of harmful gases such as CO, CO₂, and NOx, transmitting the collected data to a centralized server for processing and evaluation. To enhance accountability and regulatory enforcement, the system integrates Automatic Number Plate Recognition (ANPR), allowing authorities to identify vehicles exceeding emission limits and notify owners automatically. Alerts are generated when pollution levels surpass permissible thresholds, and information is displayed on an LCD panel as well as transmitted via connected networks. By providing immediate feedback and actionable data, this intelligent system supports sustainable urban management, promotes environmental awareness, and assists government agencies in implementing stricter emission control measures. The framework ensures proactive monitoring, contributing to cleaner air and improved public health.
