Design and Construction of Hazardous Gas Detection and Control System for Electric Vehicle Cabin

Electric vehicles (EVs) are a promising technology for achieving a sustainable transport sector due to their very low to zero carbon emissions, low noise, high efficiency, and flexibility in grid operation and integration. This chapter includes an overview of electric vehicle technologies as well as associated energy storage systems. Different types of electric-drive vehicles are presented. Also, if hazardous gas is detected inside of the cabin such as CO2 gas as a result of occupants of the vehicle, the system will open windows of the vehicle automatically. The advantage of this system is proper detection and faster response time leading to faster diffusion of the situation, compared with the manual methods. The gas sensor used in this project is MQ-7 and MQ-135 which detects the presence of hazardous gases both inside and outside of the vehicle cabin. These sensors will detect the concentration of the gas according to the voltage output of the sensor. To make the sensors operate in the control and data monitoring system, Arduino Uno was used as the microcontroller for the whole system. The circuit also includes Servo motor, buzzer, exhaust fan and LCD screen.
