Executive summary
Most of the motor vehicles always overheat to the extend of the engine pistons burning
up without the notice of the motor vehicle consent. For this reason , most of the overheating
incidences always happen and leads to even death when the whole vehicle bursts into flames.
The development of the temperature monitoring device that could detect the temperature of the
vehicle and then creates an alarming system which shows if the temperature is too high so that
the same can be corrected promptly without causing any problem.
