Research on Design and Manufacture of System to Measure and Warning Air Quality, Temperature, and Air Humidity in Cars

Air quality inside vehicles has a direct impact on the health and comfort of passengers, particularly in heavily polluted urban traffic environments. This study presents the design and development of an integrated monitoring and alert system for air quality, temperature, and humidity within automobiles. The system is built upon a combination of environmental sensors and an Arduino-based microcontroller unit. It is capable of detecting when measured parameters exceed predefined safety thresholds and provides real-time alerts to the occupants. Additionally, the system proposes automatic control solutions for the vehicle’s ventilation and humidity regulation systems in cases of excessively high or low humidity, thereby improving the overall in-cabin environment. Experimental evaluations demonstrate that the system operates reliably, with fast response times and consistent performance across a range of air quality conditions. The proposed solution enhances driver and passenger experience by ensuring a safer and more comfortable in-vehicle environment
