Individual Vehicle Air Pollution Detection and Monitoring Using IOT

Nowadays, pollution is one of the major problems in the world. One of the major contributors to pollution is from vehicle emissions. Emissions that are released directly from the cars and trucks are the primary source of vehicular pollution. Motor vehicles also pollute the air during the processes of manufacturing, refuelling, and from the emissions associated with oil refining. BS are emission standards by the Government of India to regulate the output of air pollutants from combustion engine equipment, motor vehicle. To control the pollution exhausted by vehicles, the amount of air pollution is needed to be calculated, and vehicle causing pollution must be identified. Internet of Things may become helpful in cities for monitoring air pollution from vehicles and the amount of pollution can be gathered and analysed. This system is specially designed to operate the system using a sensor network and gather information about pollutant levels discharged by the vehicles. To control the emission from the vehicle the Government has implemented a PUC certification.

PUC Certification is compulsory for all vehicles in Indian roads. It is to ensure that the vehicle is under the norms of pollution. The validity of the certificate is 6 months. After that, we must take a new certificate. To overcome this problem, our proposed system has an inbuilt system inside the vehicle that checks the continuous emission values

Project Description


              Pollution is an ever-sustaining environmental issue in today’s world. Automobile emission being the major contributor to pollution, this system can be considered as a control measure. This system focusses on developing a vehicular pollution monitoring system based on the Internet of Things (IoT). The amount of pollution emitted by the vehicles can be measured with the help of sensors interfaced to Arduino. If the sensed value goes beyond the threshold value set in the program then automatically an alert message as a warning will be sent to the vehicle owner two or three times and if they are reluctant to correct it, the message will be forwarded to the authorities. These data are finally stored in a cloud for future analysis. The main objective is to develop an innovative and time-saving system, thereby proposing a solution for environmental pollution.
