Abstract

Nowadays, the incidence of carbon monoxide (CO) gas leakage in vehicles has increased. The leaking of the vehicle exhaust system will lead to a high risk and harm to humans. Hazardous gas can affect human quality of life, such as the respiratory and blood systems, where it will harm driver and passenger brains due to a lack of oxygen in bloodstream. It primarily impacts the driver who has been driving and traveling on a long trip by way of a vehicle. The driver is supposed to have a rest and take a nap in their vehicle. Normally, the air conditioner (AC) is switched on during hot season, which ensures that the engine is often turned on which allows CO gas leakage to the vehicle. This project was created at reasonable cost to solve this issue by detecting CO gas using the MQ-7 sensor. To make this system more effective, Arduino UNO is used as a microcontroller to control both the process which are input and output. The LCD display is being used to display the concentration of CO gas in the vehicle at a ppm value. LEDs and buzzers operate as an alarm device. GSM and GPS technology are used to send a warning message with a real-time tracking device, where the location could be reported to an authorised person on longitude and latitude. In addition, this system is designed with a power window motor that automatically roll down the window when the concentration of CO gas is at danger. So, the concentration of CO gas in the vehicle can be controlled and this will avoid CO gas poisoning and death to the user.
