Fuel adulteration has become a very important and global issue nowadays. for overall development of the country transportation facilities must be better which depends on quality and purity of fuel. adulteration or mixing of various substances causing degradation and reducing the quality of fuel has become an important issue nowadays, due to which overall economy of the country is down. due to altering the properties of fuel, it doesn’t meet the specifications as per requirement. use of adulterated fuel in automobiles causes the exhaust gases to be emitted from vehicles which is a major source of urban air pollution in third world countries. adulteration of gasoline and diesel further aggravates the problem. for the prevention of adulteration, monitoring of fuel quality at the distribution point, therefore, is essential. the term “pilferage” basically refers to stealing or thefting. oil theft always results in huge economic loss, human causalities, and extremely environment pollution especially when the leaks from crude oil pipeline are not detected and repaired timely. the intelligent anti-theft system application can not only stop oil theft timely, but also prevent oil mice from stealing crude oil before-hand. an efficient automotive security system is implemented for anti-theft detection using embedded system consists of global positioning system (gps) and a wi-fi module. the system in the event of theft will send a predefined message to the owner of vehicle. the aim of this project is firstly to monitor for fuel leakage to avoid fire accidents providing safety feature where security has been an important issue. secondly an alert message will be sent when the density of the fuel changes due to the pressure or thefting. third is an alert signal or message is sent when the fuel tanker doesn’t reach the destination and its exact location and activities are monitored in real time and lastly it checks the quality of the fuel based of parameters (like density, temperature, viscosity etc.)
