Automatic PUC detection System

PUC System i.e. Pollution Under Control System is intended to check emission from in-use vehicles. If PUC is not regularly done, then it leads to incomplete combustion of fuel. This in turn leads to environmental pollution. The condition and roadworthiness of many on-road vehicles are highly unsatisfactory leading to higher exhaust emissions and road accidents. The application of PUC detection system is to detect and regulate emission of on road vehicles using communication technologies like GSM. This paper aims to give a perspective of the present inspection and maintenance practices in India outlining the gaps and scope for improve- ment in the system.
