The project on-road emission analyzer designed to measure real-time exhaust pollutants from moving vehicles using high-precision gas sensors. The system captures key gases such as CO, CO₂, HC, and NOx with improved accuracy through an embedded microcontroller-based data acquisition unit.A wireless communication module transfers the collected data to a central monitoring platform for further analysis. The device enables quick, non-intrusive testing of vehicles under real driving conditions, unlike traditional stationary emission tests. Advanced algorithms validate the measured values against pollution control norms to determine compliance. If the vehicle meets the standards, the system automatically generates a digital emission certificate.
