Abstract

Carbon monoxide (CO) is a toxic, colorless, and odorless gas that is difficult to detect. Carbon monoxide is produced in large quantities by automobile exhaust emissions. Carbon monoxide can get into the vehicle through holes in the exhaust system. Inhaling an excessive amount of carbon monoxide for an extended period has a direct influence on human health and can result in lethal carbon monoxide poisoning. To ensure that the level of carbon monoxide in the vehicle is safe, the air quality must be monitored. Drivers who must endure long drives and must rest in their automobiles will be particularly affected. When the car's air conditioner (AC) is turned on during hot weather, the engine is simultaneously turned on, generating CO leakage into the vehicle. Many people perished as a result of carbon monoxide poisoning in cars. As a result, incorporating a low-cost "Vehicle Carbon Monoxide Detector (VeCOD)" into a carbon monoxide monitoring system minimizessimilar incidents. Using an MQ-7 CO gas sensor, this research intends to construct a CO gas warning system for detecting CO in cars. To make the system more realistic, an Arduino Uno is utilized as a microcontroller to control the entire system. In addition, the LCDs the CO concentration within the car in ppm units and warns of leaks at the exhaust-to-engine connection, using an alert system consisting of an LED and a buzzer. CO concentration is divided into two levels in this project based on the output voltage of the sensor. This system would automatically warn the driver or user if a leak connection between the exhaust connection and the engine is detected, or if a dangerous level of CO in the car cabin is detected, by activating signals via LCD, LED, and buzzer to alert the driver or user to avoid carbon monoxide poisoning.
