The system contains Ultrasonic Sensor modules, Gsm module SIM800, liquid flow sensor, liquid Display (LCD) to indicate the updates. The full system is controlled by using an Arduino NANO Microcontroller. Ultrasonic sensors are characterized by low-cost and therefore the possibility of being employed in environments and situations where it's impractical to use more complex sensors. During this work, JSN-SRO4T is an ultrasonic electric telemeter module used as an ultrasonic transmitter and receiver. To begin the measurement, the trigger pin has to be made high for 15uS. This action will trigger an ultrasonic wave at a frequency of 40Hz from the transmitter and so the receiver will await the wave to return. Once the wave is returned after it gets reflected by the object, the Echo pin goes high for a particular amount of it slow which may be adequate for the time taken for the wave to return back to the sensor. By using this pulse width, we are able to measure the backlog. gsm is employed for a way communication to alert the owner of car within the style of message and a call ring, as regard of the fuel filled message and also if the fuel theft occurs the message and call indication is forwarded to vehicle owner about the fuel theft.in the project the flow level sensor is worked as ignition of car, if the fuel is flowing through flow level sensor it's normal state and if the fuel is decreasing in fuel tank and not flowing through the flow level sensor it indicates fuel theft from the vehicle .
