On-Board Diagnostics based remote emission test for Light Motor Vehicles

Electronics is becoming an indispensable part of vehicular technology. With the advancement in vehicular technology, on-board diagnostics (OBD) emission checks are included in the inspection and maintenance (I/M) program for light motor vehicles (LMV). The present work introduces a remote OBD based emission test for LMV using the android application. This application communicates with the OBD port of vehicle using ELM 327 OBD scanner. It scans the vehicle identification number (VIN), performs the emission checks, and updates the report to google sheet. Further, the google apps script (GAS) associated with google sheet is developed which performs an automated process of separating the reports based on result and mailing it to the user. Moreover, the script will also mail to the ones that are due for taking the test. The test can be easily included in the I/M program replacing the conventional tailpipe test or existing OBD checks which require more infrastructure and curbs the malpractices related to storing the report.
