Abstract
Car owners especially in these days, are facing more problems due to the high temperatures when parking the car under burning sun due to the air temperature rise inside the car and production of harmful gases. In this paper, the design and development of a smart car air cooling system with the help of a temperature sensor and carbon monoxide sensor has described. The system was developed with microcontroller, Wi-Fi module, fan, sensors and other control circuitry to manage the system to operate manually and automatically. With the help of mobile application, the owner is able to receive the information regarding the level of temperature and the percentage of gas inside the car. The system is able to begin working when the temperature reaches 30°C and stop automatically when the temperature comes below 25°C. The temperature level inside and outside of the car was measured and the highest temperature inside the car cabin was observed to be 61°C. The principle of operation and theoretical analysis was provided. The experimental results were provided with the level of temperature and percentage of gas emissions inside the car under sunlight.
