Design and development of an improved (voice alert) engine overheat monitoring unit for motor vehicle.
MetadataShow full item record
The temperature in a vehicle is a fundamental factor for its correct operation. When a failure occurs in the cooling system, irreversible damage to engine components can occur due to overheating. In the present work, and auxiliary system is implemented that alerts the driver before eventual overheating of the engine by means of sound and warning lights. The system compares the data provided by the coolant temperature sensor in real time using Arduino continuously processing the data and tallying it with the set parameters. The system starts operating when the engine reaches its optimum operating temperature. When a critical temperature is exceeded, an audible alarm will sound and the LED lights will turn on to signal the driver of the possible engine overheating occurrence. This project has been tested in all engine working conditions and it has proven to be very efficient with the conventional alert systems that do exist.
