ABSTRACT: Carbon monoxide is a gas that is colourless, odourless, and tasteless. It may experience partial combustion. Carbon monoxide has long been recognised as a silent killer. Enclosed areas or idling vehicles in garages can lead to elevated carbon monoxide levels in automobiles. The aim of this study is to develop a gas sensor capable of detecting carbon monoxide in vehicles and integrating it with the Internet of Things (IoT). This sensor can transmit data to other devices or systems and link to technologies via the Internet and sensors. The system utilises the MQ-7 sensor as a carbon monoxide detector, which the gas sensor employs to detect notifications. The Arduino IDE facilitates a connection between hardware and software through data transmission. The study uses the Blynk application to detect carbon monoxide levels on a smartphone. The smartphone’s alarm will trigger to notify the user if the CO (Carbon Monoxide) concentration is above 50 ppm. It will remain inactive if the value is beneath the threshold. Drivers can use the device as a safety measure to identify the presence of carbon monoxide in their automobiles. Conducted a test on the carbon monoxide detector to evaluate its response to an increased CO concentration of 100 ppm. Nonetheless, the objectives in this case are to guarantee their functionality and ability to detect and provide alerts that offer reliable protection against carbon monoxide exposure. This study utilised diverse systems and approaches, including Kansei Engineering (KE) and User Center Design (UCD), to determine user preferences for carbon monoxide devices during the development phase. Therefore, anticipate that the standard design process will give practitioners, especially product designers, more guidance in creating design specifications. Furthermore, it broadens the theory’s relevance to product design and development.
