Abstract

In most situations, each vehicle including car has a cooling system. In a cooling system, a radiator is an important component to maintain the temperature of an engine. There are two different types of radiator fans which are mechanical fans and electrical fans. Belt-driven fan and clutch fan are two names that are occasionally used as mechanical fan. The mechanical fan slows when the vehicle does. This might happen in a traffic jam or if the engine is idling while waiting for the green light. Due to a lack of airflow while the car is moving slowly, the engine might be overheated. They degrade the performance of the car. Nowadays, electrical radiator fans are currently capable of resolving mechanical radiator fan issues but it still using a thermostat. A thermostat is used to regulate the fan. However, there has been situations when the electrical fan thermostat stuck due to corrosion which caused the fan running continuously or not spinning. Therefore, several systems have been proposed to overcome the issue. In this paper, a vehicle real-time temperature monitoring and control have been proposed. In this system, Arduino Uno, temperature sensor, LCD display, keypad and DC fan are utilized as the main hardware, while Arduino Uno and the Arduino IDE as software to write and upload computer code to the physical board. The temperature sensor is attached to the coolant, and once it does, the DC fan will begin to spin. User able to set the desired temperature for the engine, so that the DC fan start to spin. The air from the DC fan will decrease the temperature of engine. As a result, circuit has been constructed and simulation has been done. By implementing this system to the car engine, user able to know their engine temperature in real time and take action if necessary. Experiment results show an average of 4.12 minutes is taken to cooldown the coolant mixture to less than 45 °C. The experiment also demonstrates that a DC fan can save 48.88% of the cooling time required to cool down the coolant mixture. Lastly, the experiment results show that the DC fan with an average speed of 3193 rpm is stable and acceptable to be used in all experiments.
